Abstract

The mechanism for outstanding resistance to He-ion irradiation-induced hardening of a novel dispersion-precipitation strengthened NiMo alloy has been investigated. Microstructural observations show the interface between Mo2C micro-particles and Ni matrix and between SiC nanoparticles and Ni matrix can effectively trap He bubbles, thus synergistically inhibiting the formation and growth of the dissociated He bubbles in the Ni matrix. It suggests that the reasonable high amounts of well-dispersed Mo2C micro-particles and SiC nanoparticles can effectively improve the inhibition efficiency of irradiation-induced hardening and are beneficial for the optimization and design of irradiation-resistant Ni-based alloys.

Abstract

Exploring efficient and stable non-precious metal electrocatalysts for oxygen reduction reaction in neutral and alkaline solutions is of great importance for metal-air batteries. Herein, an efficient and stable electrocatalyst with CoNi nanoalloy (10-20 nm) uniformly embedded in porous N-doped carbon framework (CoNi-NCF) for neutral and alkaline primary Al-air batteries is prepared and studied. The CoNi-NCF electrocatalyst shows superior ORR performance in terms of half-wave potential of 0.91 V in 0.1 M KOH solution and 0.64 V in 3.5 wt% NaCl solution, outperforming those of the commercial Pt/C catalyst. Supported by in situ electrochemical Raman spectra and density functional theory calculations, the rich dual active sites of CoNi nanoalloy and porous N-doped carbon contributes to the outstanding ORR performance. Impressively, when employed as a cathode catalyst in both aqueous and solid flexible Al-air batteries, the CoNi-NCF-based Al-air batteries show the highest discharge performance, long-time durability and high flexibility, demonstrating the promising potential for practical application.

Abstract

In present study, Fe-based composite layers were fabricated on steel substrate by laser cladding with or without the addition of Nb and B4C in Fe-based alloy powders. The phase composition, microstructure evolution, microhardness and wear properties of Fe-based composite layers were studied. The results showed that the phases in the Fe-based composite layer were mainly α-Fe, Fe2B, Cr7C3 and Cr23C6. The addition of Nb and B4C resulted in the in-situ formation of NbC phase, an increase in the amount of Fe2B phase, and the refinement of the microstructure in the Fe-based composite layer. The microhardness of the Fe-based composite layer was increased by 269.5 HV0.5 and the wear resistance was improved to about 1.5 times the original wear resistance when the 5% Nb and 5% B4C powders were added. The wear mechanisms of both two Fe-based composite layers were abrasive wear and adhesive wear.

Abstract

This paper presents the microstructure evolution and corrosion resistance of Fe-18wt.%Cr-1wt.%Mo-3.5wt.%B alloy against molten zinc at 520 °C. The objective of this study is to obtain Fe-B alloy with superior corrosion resistance through microstructure regulation and to reveal the underlying corrosion mechanism. The results show that the metal matrix of as-cast Fe-Cr-B alloys have undergone a transition from α-(Fe, Cr, Ni) solid solution into γ-(Fe, Cr, Ni) solid solution, while the eutectic boride is further refined with the increasing of Ni addition in the steels. The corrosion resistance of the Fe-Cr-B alloys has significantly been enhanced, with an optimal Ni addition at 10 wt%. Thermodynamic calculations and EPMA results show that Ni mainly exists in the matrix, leading to the transformation of the matrix structure. The improvement of corrosion performance can be attributed to two factors: the refined boride network in Ni-modified Fe-Cr-B alloy act as a barrier for Fe/Zn reaction, and the formation of face-centered cubic (fcc) structure also contributed to improve corrosion resistance owing to a more densely packed structure compared to body-centered cubic (bcc) structure. In the initial stage of corrosion, the de-alloying of Ni occurs first, which result in the transformation from γ-(Fe, Cr, Ni) to α-(Fe, Cr, Ni). Corrosion mechanism for test alloys in molten zinc may be mainly dominated by the formation and propagation of cracks in the borides. The cracks initiated due to the discrepancy in thermal expansion coefficients between Fe-Zn phases and the borides.

Abstract

Based on the Fe Cr B alloy, the Fe 12Cr 1.5B xAl (x = 0, 2, 4, 6 and 8 wt%) alloys were designed by adding Al. The as-cast microstructure and cyclic oxidation behavior have been investigated extensively in this study. The results reveal that the as-cast microstructure of Fe Cr B alloy consists of martensite (bcc), retained austenite (orthorhombic) and M2(B,C)-bct, M7(C,B)3-hcp, M23(C,B)6-complex fcc boron-carbides, gradually changing to α-(Fe,Al,Cr) solid solution (bcc), M2(B,C)-bct, M7(C,B)3-hcp, M23(C,B)6-complex fcc boron-carbides and Fe3Al intermetallic compound with the increasing of Al contents. The oxidation kinetics of all alloy samples follow a parabolic oxidation kinetic law. The oxidation rate constant kp in Al-free Fe Cr B alloy is nearly four times of that in Fe Cr B 8Al alloy. The additions of Al refine the grains and make the distribution of elements more uniform, which results in forming a continuous and dense oxide film containing Al2O3 oxide with excellent fluidity and thermal stability, remarkably enhancing the high temperature oxidation resistance of Fe Cr B Al alloy.

Abstract

Ni-Mn-Ga microfiber with a diameter of 80 μm was produced by glass-coated melt spinning method. The martensitic transformation temperature, TM, and the reverse transformation temperature, TA, is 279 K and 290 K, respectively. The as-cast microfiber shows nearly fully recoverable superelastic strain as large as ~10%, and perfect strain-magnetization effect, as the stress-induced martensite has lower initial susceptibility and higher saturation magnetization than the austenite. It will be a potential non-destructively and noncontactually monitor sensor material.

Abstract

The mechanical behavior of cast nickel-based superalloy Inconel 718 was investigated via hot tensile experiments at 650 °C, 800 °C, and 950 °C to understand the thermal instability of its metallurgic microstructure. Test specimens, which were machined from investment casting, were subjected to a standard heat treatment. Post-tensile testing, microstructure characterization, and fractography observations were conducted with a scanning electron microscope (SEM) and a transmission electron microscope (TEM). The resulting data revealed that the deterioration of toughness and ductility occurred at temperatures above 650 °C. Numerous shear bands and lattice mismatch suggested that plastic deformation through slip movement dominated the ductile fracture mode of the nickel-based superalloy at 650 °C. In contrast, surficial microporosity and grain boundary weakening caused early brittle rupture, before the material yielded, at 800 °C. Significant strain accumulation within grains contributed to plastic flow in the direction of the applied stress load, resulting in intergranular and transgranular fracture at 950 °C. Microstructural evidence displayed the interface debonding between the carbide and the matrix at 950 °C, indicating the temperature limitation of the carbide pileup.

Abstract

Effective oxidation control of metal materials is a long-standing challenge. Here we show a new strategy for oxidation control induced by nanoparticles (NPs). The results demonstrate that the in situ formed NPs can promote the formation and growth of a continuous and dense protective oxide scale while enhancing its adhesion with the matrix. Furthermore, the assembly of NPs on the grain boundaries (GBs) and phase boundaries (PBs) can be effective in stifling the inward diffusion of oxygen ions and the outward diffusion of cations. The effectiveness of this approach is verified in FeCr alloys in high temperature conditions. Our approach can break through the inherent limitations of conventional alloying treatment, e.g. the detrimental element interaction, the high costs and limited availability of noble metals and rare earth elements, which may pave a new avenue for the remarkable improvement in the oxidation resistance of metal materials.

Abstract

In this work, in situ nanoparticles (TiB2 and TiC) can be demonstrated to induce significant improvement in the oxidation resistance of Fe-12 wt.%Cr-3.5 wt.%B alloys. To unravel the roles of nanoparticles in the anti-oxidation of Fe-12 wt.%Cr-3.5 wt.%B alloys, samples with various nanoparticle contents were synthesized to investigate their oxidation resistance. Results show that nanoparticles facilitate the formation of a continuous and dense Cr2O3 protective film and enhance its adhesion with the matrix. Furthermore, the nanoparticle assembly on the surface of borides can inhibit the inward diffusion of oxygen ions and the outward diffusion of cations, thereby effectively controlling the growth of oxide scales.

Abstract

In this paper, the effect of heat treatment (760–1060 °C) on tribological behavior of selective laser melted Ti6Al4V alloy against Si3N4 counter-ball under different applied loads was investigated. Results show the wear rate of as-built Ti6Al4V alloy increased firstly and then gradually decreased with increasing the heat-treatment temperature, which obtained the lowest value when the heat treatment temperature was 1060 °C, exhibiting the best wear resistance. The higher applied load led to larger wear rate and lower coefficient of friction. The wear mechanism was strongly dependent on the microstructure transformation, micro-hardness and applied load, which was discussed in detail.

Abstract

CoCrFeNi and CoCrFeNiAl0.3 high entropy alloys reinforced with in-situ oxide nanoparticles have been successfully fabricated by mechanical milling in combination with hot pressing and hot extrusion. The as-fabricated CoCrFeNi samples exhibited an ultrafine grained microstructure with in-situ Cr2O3 oxide nanoparticles formed during hot pressing and extrusion process and distributed both on grain boundaries and in grain interiors. Increasing extrusion temperature from 1000 to 1100 °C caused a significantly increase of grain size from 700 nm to 2.5 μm owing to recrystallization and growth of the recrystallized grains, as well as the coarsening of Cr2O3 nanoparticles with their mean size increasing from 57 to 140 nm. When adding Al elements, finer Al2O3 nanoparticles (mean size: 30 nm) formed in the CoCrFeNiAl0.3 high entropy alloy, leading to refinement of the grains (mean size: 504 nm) due to their pinning effect on grain boundary immigration. After T6 heat treatment, the CoCrFeNiAl0.3 high entropy alloy demonstrated improved mechanical properties with yield strength of 1335 MPa, ultimate tensile strength of 1346 MPa and an elongation to fracture of 7.9%. With quantitative analysis based on the current models, it was concluded that grain boundary strengthening and Orowan strengthening acted as the dominant strengthening mechanisms.

Abstract

In this study, the SiC/Al-Zn-Mg-Cu nanocomposites were fabricated using high energy ball milling combined with spark plasma sintering (SPS) and hot extrusion. The microstructure and mechanical properties were investigated by utilizing X-ray diffraction (XRD), scanning electron microscopy (SEM) and high resolution transition electron microscopy (HRTEM) analysis as well as tensile tests. The results showed that the as-extruded SiC/Al-Zn-Mg-Cu nanocomposite samples demonstrated a microstructure consisting of ultrafine α-Al grains, dispersed SiC nanoparticles and nano-scaled T phases probably formed by dynamic precipitation during extrusion. After T6 heat treatment, the coarsening of α-Al grains, dissolution of T phases and consequently the precipitation of fine η′ phases occurred, leading to a simultaneous increase of the strength and ductility. With increasing the content of SiC nanoparticles from 1 vol% to 3 vol%, the yield strength (YS) and ultimate tensile strength (UTS) increased from 456 and 528 MPa to 580 and 588 MPa (27.2% and 11.4% increase), respectively while the elongation to fracture decreased slightly from 11.8% to 10.2% (13.6% decrease). Various strengthening mechanism calculation results show that Orowan strengthening was mostly contributed to the improved strength of the T6 heat treated SiC/Al-Zn-Mg-Cu nanocomposites.

Abstract

Nickel-based superalloys have been widely used in manufacturing turbine blades, vanes, and discs of aircrafts and power generators that serve in challenging environment. In order to meet the requirements for rapid manufacturing of these large-scale and high-performance components, the extreme high-speed laser metal deposition (EHLMD) technology have attracted great attention in recent years. The EHLMD technology can significantly improve the efficiency compared with conventional laser metal deposition (LMD). Meanwhile, the solidification condition and the resultant microstructures and mechanical properties can also be dramatically changed. In this study, a high chromium superalloy (K648) has been additively manufacturing by using EHLMD for the first time. The key process parameters and the resulted microstructure and mechanical properties are investigated. The results have shown that the most important factors affecting the height, width, and depth of the single-track deposit of EHLMD K648 superalloy are powder feeding rate, laser power, and scanning speed, respectively. The height and the width of the deposits are the largest when the laser power, scanning speed, and the powder feeding rate are 1400 W, 25 m/min, and 30 g/min. There exist some incomplete fusions in the interlayer region and some pores in the interior region of the multi-track-multi-layer deposits. Columnar grains grow in the build direction within each layer, while equiaxed grains tend to form in the interlayer region. The average value of microhardness of EHLMD K648 superalloy is about 298.1 HV. The ultimate strength of EHLMD K648 superalloy is slightly lower than that of the forging GH648 superalloy but higher than that of the conventional LMD K648 superalloy.

Abstract

Ti–6Al–4V alloys are utilized in various industrial applications. Here, the effect of heat treatment on the microstructural evolution and mechanical properties of the Ti–6Al–4V alloys, which were fabricated by selective laser melting (SLM), was investigated. The as-fabricated-1133 K sample possessed a significantly higher ductility than that of the as-fabricated sample. This was attributed to the precipitation of the micro/nanoscale β and athermal ω phases that was accompanied by the equiaxial transformation of the β columnar grains.

Abstract

In this paper, the high-temperature oxidation behaviors at 900 °C of the conventional laser metal deposition (LMD) and extreme high-speed laser metal deposition (EHLMD) high chromium K648 superalloys were comprehensive studied. The experimental results reveal that the oxidation resistance of the LMD K648 superalloy is better than the EHLMD K648 superalloy. The oxidation films of LMD and EHLMD K648 superalloy consists of continuous Cr2O3 film and an internal wedge-shaped Al2O3. The oxidation process is mainly controlled by the outward diffusion of oxide-forming elements and the inward penetration of oxygen.

Abstract

In this work, we employed first-principles calculations to investigate the stability, electronic structures, mechanical and thermodynamic properties of FexAlyCz compounds which were first observed in Fe-Cr-B-Al-C alloy. The results reveal that the FexAlyCz compounds are thermodynamically stable, and the addition of C element improves the stability of FexAlyCz compounds. These FexAlyCz compounds display disparate anisotropy according to different calculated 3D curved surfaces of Young's modulus and anisotropic index. The Fe3AlC compound has the biggest shear modulus, bulk modulus and Young's modulus with the values of 141.2 GPa, 212.6 GPa and 346.8 GPa, respectively, which indicates that the Fe3AlC compound has the largest rigidity, lateral deformation resistance and good solid compressibility under static pressure. The ratio of G/B shows that FeAl and Fe3AlC are brittle phases, while the Fe3Al and FeAl3 phases appear to be ductile. The calculated electronic structure reveals that the bonding characteristics of the FexAlyCz compounds are the mixture of both metallic and covalent bonds, which also exhibits anti-bond effects. The Fe3AlC compound has the biggest Debye temperature of 702.2 K. Meanwhile, the hardness of Fe3AlC is 19.4 GPa which is three times of the Fe3Al compound. The results obtained in this study provide a theoretical basis for the applications of Fe3AlC compound in Fe-Cr-B-Al-C alloys.

Abstract

The effect of temperature on the oxidation resistance of a novel wear-resistant Fe-10Cr-1.5B-6Al-0.3C-0.8Mn-0.6Si alloy is investigated. The mass growth rate shows that this alloy exhibits superior oxidation resistance at 900 °C. As the oxidation temperature increases from 900 °C to 1100 °C, the structure of the observed oxide scales transforms from a porous bilayer to a flat monolayer, while the oxidation rate increases sharply. The selective oxidation of Al suppresses the outward diffusion of Cr and Mn to form MnCr2O4 oxides in the monolayer oxide scale, thereby decreasing the oxidation resistance at 1100 °C.

Abstract

Additive manufacturing Ti6Al4V alloys have found their potential applications in artificial teeth and hip joints. In this work, the relationships between wear resistance, hardness and microstructure of Ti6Al4V alloys fabricated using various routes were investigated in artificial saliva. The results indicate that comparing with wrought and wrought + heat treated (HT) samples, the as-SLMed samples with hcp-α′ martensite and few bcc-β phase exhibit higher hardness (∼410 HV) and better wear resistance. The as-SLMed samples, however, exhibit the worst wear resistance when wear direction is parallel to the molten pool line on XOZ-plane due to containing the softer fusion zone. Finally, the wear mechanism is discussed in detail, mainly including the abrasive and adhesive wear mechanism. The high hardness of matrix as well as the strong adhesion between the hardened layer, oxide layer and matrix are indispensable conditions for maintaining the optimum wear resistance.

The results show that the main phases of the K648 superalloy are γ-Ni, γ′, α-Cr and M23C6. The microstructure from the bottom to the middle region is mainly composed of epitaxially grown columnar dendrites, and the microstructure in the top region is mainly equiaxed grains. Element segregation exists in the LMD K648 superalloy. The average microhardness of the LMD K648 superalloy is about 220.5HV. The tensile strengths of LMD K648 superalloy show obvious anisotropic characteristics and the maximum ultimate tensile strength is about 833 MPa.
