Abstract: Correlation between the feedstock powder and the as-printed products is well expected in laser powder bed fusion (LPBF). However, the inheritance/heredity relationship between the feedstock powder and the products remains broadly overlooked since most atomized powders are printed without any modification. This study addresses the inheritance issue through comparing the hydrogenation/dehydrogenation (HDH) Ti powder with the ball-milled (BM) Ti powder, as well as the respective as-printed samples. Rietveld refinement, focused ion beam, electron backscatter diffraction, and transmission electron microscopy are employed to characterize the microstructure; uniaxial tensile tests and fractographic observation are performed for the mechanical analysis; single-track finite element simulations are conducted to reveal the varied powder-bed properties. A “core-shell” powder structure has been generated through the ball milling modification. Nano-crystallites in the “shell” and stress-induced twins have brought significant grain refinement to the BM powder. A β-to-αm massive transformation has been observed in the samples printed using HDH powder, whereas the microstructure changes to fully-martensitic when using BM powder as the feedstock. Excellent mechanical performance (∼1000 MPa tensile strength with ∼20% ductility) have been achieved through inheriting the fine microstructure and oxygen content from the BM powder, which are induced by the powder modification process. This study has therefore unveiled the comprehensive correlation between the feedstock powder and the as-printed Ti, highlighting a novel methodology for developing additively-manufactured, cost-effective, and high-performance materials through tailoring the feedstock powder.

Abstract: Iron (Fe) is a potent β-stabaliser, capable to replace costly alloying elements such as V and Mo in forming cost-affordable, biomedical Ti alloys. Selective Laser Melting (SLM) is a mainstream additive manufacturing (AM) technology, competent in realizing near-net shaping of complex, quality parts. In this study, Ti-5Fe alloy was prepared by SLM using elemental powders of Fe and modified hydrogenated-dehydrogenated (HDH) Ti, aiming at providing a cost-affordable candidate biomedical Ti alloy. It is found that, under the “optimum printing parameters”, homogeneous distribution of Fe is possible by the in-situ alloying process. After further efforts in terms of impurity scavenging and heat treatment, the in-situ alloyed Ti-5Fe shows a combination of high strength, good ductility and good biocompatibility. The best mechanical properties achieved are ~865 MPa for tensile strength and ~12% for elongation. This study demonstrates the capability of laser in-situ alloying additive manufacturing in developing cost-affordable and high quality biomedical Ti materials.

Abstract: An abnormal two-way shape memory effect (TWSME) is found in a rapidly solidified Ni51Ti49 alloy strip undergoing constrained aging treatment at relatively low temperatures (e.g., approximately below 385 degrees C for aging time of 1 h), which embodies the bending of the strip toward constrained position during martensitic transformation on cooling, showing stark difference from normal TWSME. The abnormal TWSME of the alloy is caused by weaker coherent stress field produced by ultrafine nano-sized Ni4Ti3 precipitates than the residual stress field, whereas the latter dominates martensitic transformation and leads to bending with the direction opposite to that of normal TWSME.

Abstract: A porous Ni50.8Ti49.2 shape memory alloy prepared by space holder assisted conventional sintering has been characterized via the micro-computed tomography (micro-CT). After proper image processing to remove the artifacts from the original reconstructed slices, the three-dimensional visualization, together with the size, shape and local structure of the pores have been obtained from the reconstructed volume. Primary pores with a volume fraction of 20.2% duplicate the size and morphology from the space holder particles and the space between the elemental nickel and titanium powders as raw materials, and segment the matrix into small volumes with an average diameter of around 220 mu m and a distance of around 125 mu m away from each other. This configuration in the porous Ni50.8Ti49.2 alloy can stall the propagation of martensite and lead to a gradual transformation. (C) 2015 The Authors. Published by Elsevier Ltd.

Abstract: We present a study of the structure of hadronic events recorded by the L3 detector at LEP at the center of mass energies of 161 and 172 GeV. The data sample corresponds to an integrated luminosity of 21.25 pb-1 collected during the high energy runs of 1996. The distributions of event shape variables and the energy dependence of their mean values are well reproduced by QCD models. From a comparison of the data with resummed second order QCD calculations, we determine the strong coupling constant at the two energies. Combining with our earlier measurements we find that the strong coupling constant decreases with increasing energy as expected in QCD.

Abstract: A search for excited leptons $\rm e^*,~\mu^*, ~\tau^*$ and $\nu_{\rm e}^*$ in $\rm e^+e^-$ collisions at $\rm \sqrt{s}$ = 161 GeV is performed using the $\rm 10.8 ~pb^{-1}$ of data collected by the L3 detector at LEP. No evidence has been found for their existence. From an analysis of the expected $\ell^*\ell^*$ pair production in the channels $\rm ee\gamma\gamma$, $\rm \mu\mu\gamma\gamma$, $\rm \tau\tau\gamma\gamma$, $\rm eeWW$, and $\rm \nu\nu\gamma\gamma$, the lower mass limits at 95\% C.L. are 79.7 GeV for $\rm e^{*}$, 79.9 GeV for $\mu^{*}$, 79.3 GeV for $\tau^{*}$ and 71.3 GeV for $\nu_{\rm e}^{*}$ assuming the same couplings as for standard leptons. From an analysis of the expected $\ell\ell^*$ single production in channels $\rm ee\gamma$, $\mu\mu\gamma$, $ \tau\tau\gamma$, $\rm \nu_{e}eW$ and $\nu\nu\gamma$, the upper limits on the couplings $\lambda/m_{\ell^*}$ up to $m_{\ell^{*}}$ = 161 GeV are determined.

Abstract: A search for unstable sequential neutral and charged heavy leptons has been made at center-of-mass energies 130 and 136 GeV with the L3 detector at LEP. The neutral leptons are assumed to decay via mixing to electrons and muons. No evidence for their existence was found. We exclude unstable Dirac neutrinos for masses below 59.3 (57.9) GeV and unstable Majorana neutrinos below 48.6 (47.2) GeV if the neutrino couples to the electron(muon) family. We exclude unstable charged heavy leptons for masses below 61 GeV for a wide range of the associated neutral lepton mass.

Abstract: A search for supersymmetric particles (charginos, neutralinos, sleptons and stop quarks) has been performed with data collected by the L3 detector during the November 1995 run of the LEP collider at centre of mass energies between 130 and 140 GeV with a total integrated luminosity of 5.1 pb−1. We observe no signal for supersymmetric particles and we set improved exclusion limits on their production cross sections and masses.

Abstract: Using the data recorded with the L3 detector at LEP, we study the process e + e − → μ + μ − ( γ ) for events with hard initial-state photon radiation. The effective centre-of-mass energies of the muons range from 50 GeV to 86 GeV. The data sample corresponds to an integrated luminosity of 103.5 pb −1 and yields 293 muon-pair events with a hard photon along the beam direction. The events are used to determine the cross sections and the forward-backward charge asymmetries at centre-of-mass energies below the Z resonance.

Abstract: We report on a search for the excited leptons e ∗ , μ ∗ , τ ∗ and ν ∗ in e + e − collisions at s = 130-140 GeV using the L3 detector at LEP. No evidence has been found for their existence. From an analysis of the expected pair produced l ∗ l ∗ in the channels eeγγ, μμγγ, ττγγ, eeWW, and ννγγ, we determine the lower mass limits at 95% C.L. of 64.7 GeV for e ∗ , 64.9 GeV for μ ∗ , 64.2 GeV for τ ∗ , 57.3 GeV (eW decay mode) and 61.4 GeV (νγ decay mode) for ν ∗ . From an analysis of the expected singly produced ll ∗ in the channels eeγ, μμγ, ττγ, νeW and ννγ, we determine upper limits on the couplings λ m l ∗ up to m l ∗ = 130 GeV .

Abstract: We have investigated the dislocation structures formed in the near surface region of ion implanted coarse-grained copper (grain size 460 μm) using transmission electron microscopy. Ti and Zr ions were implanted into copper using a vacuum arc ion source. The ion energy was about 100 keV and the applied (incident) dose was 1 × 10 17 cm −2 . We find that Ti and Zr ion implantations produce a developed dislocation structure in the Cu subsurface layers. The dislocation structure changes form cell-net and cell dislocation structures at shallow depth to individual randomly distributed dislocations at greater depth. The maximum dislocation density in copper is 6.1 × 10 9 cm −2 for Ti and 11.4 × 10 9 cm −2 for Zr. The thickness of the modified copper layer with high dislocation density is up to 20 μm for Ti and 50 μm for Zr. Microhardness measurements vs. depth and dopant concentration profiles are presented. The long range effect is explained in terms of a model of static and dynamic mechanical stresses formed in the implanted surface layer.

Abstract: We have searched for anomalous Z → γγγ events with the L3 detector at LEP. No significant deviations from the expected QED e+e− → γγγ events are observed. The branching ratio upper limit for a compoite Z decaying directly into three photons is found to be 1.0 × 10−5 at 95% C.L. The branching ratio upper limits for the process Z → γX, X → γγ are in the range of 0.4 to 1.3 × 10−5, depending on the mass and width of the scalar particle X. In the context of a model with magnetic monopoles coupling to the Z, we find BR(Z → γγγ) < 0.8 × 10−5 at 95% C.L.; this results in a lower mass limit of 510 GeV for a magnetic monopole., Facultad de Ciencias Exactas

Abstract: We have measured the branching fractions for the hadronic τ decays, τ→π/Knπ°v (0 ≤ n ≤ 3), with the L3 detector at LEP. Multiphoton final states are analyzed using the fine-grained, high-resolution electromagnetic calorimeter. The decay channels are identified using a neural network method. The results are: BR(τ→π/Kv) = (11.82 ± 0.26 ± 0.43)%, BR (τ→π/Kπ°v) = (25.05 ± 0.35 ± 0.50)%, BR(τ→π/ K2π°v) = (8.88 ± 0.37 ± 0.42)%, BR(τ→π/K3π°v) = (1.70 ± 0.24 ± 0.38)%, where the first error quoted is statistical, the second systematic., Facultad de Ciencias Exactas

Abstract: The pitting corrosion behavior in deaerated 0.05M NaCl solution of titanium ion implanted aluminum has been investigated. The samples were implanted with Ti ions using a Mevva high current metal ion implantation facility at doses ranging from 2×10 15 to 2×10 17 ions/cm 2 and with ion energy from 30 to 120 keV, and the resultant Ti depth profiles were measured with Rutherford backscattering spectrometry (RBS). The pit density was decreased by up to two orders of magnitude relative to the unimplanted samples. The pitting potential increase ranged from 0.1 to 0.3 V. The pitting potential increase of the high dose samples was limited by pit formation at pre-existing scratches whereas the majority of the surface was free of pits to potentials up to 5 V SCE .

Abstract: The macroparticle contamination of vacuum-arc-deposited thin films generated by a plasma source with an optional axial magnetic field is studied. Emphasis is placed on the macroparticle flux near the discharge axis. The arc current, metal species, deposition system geometry and axial magnetic field strength are varied. Distribution functions for macroparticles of Pb, Ag, Cu, Pt, W, and Ni are determined, normalized to the film thickness deposited or the charge transferred. The application of the axial magnetic field leads to a considerable reduction of the normalized macroparticle flux since the plasma is effectively focused by the field, whereas the macroparticle production is not influenced. The macroparticle content normalized to the deposited film thickness is reduced to about 20-35% of that without an additional magnetic field. >

Abstract: A method for the plasma synthesis of metallic and composite thin films with atomically mixed interfaces is described. A large number of metal species can be applied and surface structures can be fabricated including films of metals and alloys, compounds including ceramics, and tailored multilayers. The added species can be energetically implanted below the surface or built up as a surface film with an atomically mixed interface with the substrate. A vacuum are produced metal plasma is used, and by adding a gas to the plasma region compound films can also be formed. The process parameters can be varied to fabricate a wide range of surface structures at the atomic level. We have demonstrated the method by synthesizing a number of metallic films as well as oxide and nitride films, including those described here: an yttrium film on silicon with an atomically mixed transition zone; a quarter-micron thick film of Pt on and mixed into Al; an Y/Ti multilayer structure in which the first and last layers were ion stitched to the material below; and an Al2O3 film on steel with a mixed bonding layer about 1000 A thick. Here we describe the background of the technique and the experimental results that we have obtained.

Abstract: We have carried out some exploratory investigations of the effect of metal ion implantation on the optical transmission characteristics of glass. The implants were done using the vacuum-arc-based high current metal ion implantation facility developed at Berkeley. The implanted doses were from 3 × 10 16 to 1 × 10 17 cm −2 and the energy was mostly 60 keV. A range of different metal ion species was used, including C, Al, Si, Ti, Fe, Ni, Cu, Y, Ag, Pt and Au. We used soda lime-silica glass (window glass), boron-silica glass (microscope slides), and tin oxide coated glass. The transmission of the glass samples to optical radiation in the wavelength range 300 to 2400 nm was measured. Here we outline the procedure and describe the results of the optical transmission measurements.

Abstract: Local multiplicity fluctuations in hadronic Z decays are studied using the L3 detector at LEP. Bunching parameters are used for the first time in addition to the normalised factorial moment method. The bunching parameters directly demonstrate that the fluctuations in rapidity are multifractal. Monte Carlo models show agreement with the data, reproducing the trend, although not always the magnitude, of the factorial moments and bunching parameters., Facultad de Ciencias Exactas

W-pair events produced in e+e− interactions between 161 GeV and 172GeV centre-of-mass energy are selected in a data sample corresponding to a total luminosity of 21.2 pb−1. The mass and total decay width of the W boson are determined to be MW = 80.75−0.27+0.26(exp.) ± 0.03 (LEP) GeV and ΓW = 1.74−0.78+0.88(stat.) ± 0.25(syst.)GeV, respectively. Limits on anomalous triple-gauge-boson couplings, γWW and ZWW, are determined, in particular −1.5 < δZ < 1.9 (95% CL), excluding vanishing ZWW coupling at more than 95% confidence level., Facultad de Ciencias Exactas

Abstract: We report on the measurement of W-boson pair-production with the L3 detector at LEP at an average centre-of-mass energy of 172.13 GeV. In a data sample corresponding to a total luminosity of 10.25 pb−1 we select 110 four-fermion events with pairs of hadronic jets or leptons with high invariant masses. Branching fractions of W decays into different fermion-antifermion pairs are determined with and without the assumption of charged-current lepton universality. The branching fraction for hadronic W decays is measured to be: B(W → hadrons) = 64.2+3.7−3.8 (stat.) ± 0.5 (syst.) %. Combining all final states the total cross section for W-pair production is measured to be: σWW = 12.27+1.41−1.32 (stat.) ± 0.23 (syst.) pb. The results are in good agreement with the Standard Model., Facultad de Ciencias Exactas

Abstract: A measurement of the $\mathrm{K^0_s}$ and $\Lambda$ inclusive production rates and momentum spectra in two- and three-jet events is presented. On the basis of about 3.1~million Z decays collected with the L3 detector at LEP, we observe that the production of these particles is well modeled by string fragmentation.

Abstract: A search for the neutral Higgs boson in the processes e(+)e(-) --> Z --> H-0 gamma --> and e(+)e(-) --> Z --> Z*H-0 --> has been performed using 2.8 million hadronic Z decays collected with the L3 detector at LEP from 1991 through 1994. No evidence for these processes has been observed. Upper limits at 95% confidence level for the corresponding cross sections have been set and the results have been compared with theoretical predictions beyond the Standard Model.

Abstract: We report on measurements of e+e− annihilation into hadrons and lepton pairs. The data have been collected with the L3 detector at LEP at centre-of-mass energies between 130 and 189 GeV. Using a total integrated luminosity of 243.7 pb−1, 25864 hadronic and 8573 lepton-pair events are selected for the measurement of cross sections and leptonic forward-backward asymmetries. The results are in good agreement with Standard Model predictions.

Abstract: The results of the searches for neutral Higgs boson production in the process e + e − → Z ∗ H 0 are reported, focusing on Higgs boson masses below 70 GeV. The data sample consists of three million hadronic Z 0 decays collected by the L3 experiment at LEP from 1991 through 1994. No signal is found leading to a lower limit on the mass of the Standard Model Higgs boson of 60.2 GeV at 95% C.L. These results are also interpreted in the framework of the General Two Doublet Model and limits on the nonstandard Higgs boson production through the process e + e − → Z ∗ h 0 are set. A lower limit of 66.7 GeV at 95% C.L. is obtained for the case where the Higgs decays into an invisible final state.

Abstract: Using the data collected by the L3 experiment at LEP from 1991 to 1995 at energies around the Z mass, a measurement of the weak anomalous magnetic dipole moment, awτ, and of the weak electric dipole moment, dwτ, of the τ lepton is performed. These quantities are obtained from angular distributions in e+e−→τ+τ−→h+ν̄τh−ντ, where h is a π or a p. The results are: Re(awτ)=(0.0±1.6±2.3)×10−3, Im(awτ)=(−1.0±3.6±4.3)×10−3 and Re(dwτ)=(−0.44±0.88±1.33)×10−17e·cm. This is the first direct measurement of awτ., Facultad de Ciencias Exactas

Abstract: The inclusive production of 77 mesons has been studied using 1.6 million hadronic Z decays collected with the L3 detector. The q multiplicity per event, the multiplicity for two-jet and three-jet events separately, and the multiplicity in each jet have been measured and compared with the predictions of different Monte Carlo programs. The momentum spectra of 7,1 in each jet have also been measured. We observe that the measured v momentum spectrum in quark-enriched jets agrees well with the Monte Carlo prediction while in gluon-enriched jets it is harder than that predicted by the Monte Carlo models., Facultad de Ciencias Exactas
