Abstract

The polarization of the secondary protons in the (p,2p) reaction with the S - shell protons of nuclei 4He, 6Li, 12C, 28Si, 40Ca was measured at 1 GeV unpolarized proton beam. The spin correlation parameters Cij for the 4He and 12C targets also were for the first time obtained as well. The polarization measurements were performed by means of a two - arm magnetic spectrometer, each arm of which was equipped with the multiwire proportional chamber polarimeter. This experiment was aimed to study a modification of the proton - proton scattering matrix in the nuclear medium., Comment: 28 pages, 7 figures, 6 tables, Sumitted th the journal "Physics of Atomic Nuclei"

Abstract

One of the current tasks of materials science is to increase the fatigue resistance of materials used in the creation of promising and modern implant designs. It is known that the formation of an ultrafine-grained (UFG) structure leads to a noticeable increase in the mechanical properties of metallic materials, but an increase in strength is not accompanied by a corresponding increase in fatigue resistance. Another feature of high-strength alloys is their increased sensitivity to stress concentrators and the surface roughness parameter. As a rule, fatigue failure begins with the formation of surface defects that turn into cracks and, accordingly, the state of the surface plays an important role in the fatigue behavior of the product. Surface plastic deformation methods allow to increase the level of properties and surface quality, among which it is worth highlighting non-abrasive ultrasonic finishing (NAUF)-pulse-hardening finishing using ultrasonic vibrations. This study is aimed at studying the effect of non-abrasive ultrasonic finishing on the fatigue resistance of samples with a stress concentrator made of Grade 4 commercially pure titanium in an ultrafine-grained structural state. In the course of the work, a surface study was carried out after non-abrasive ultrasonic finishing, including an assessment of residual stresses. Comparative fatigue tests of samples with a V-shaped annular groove were carried out under conditions of bending with rotation at a frequency f=50 Hz, with a symmetrical loading cycle and a test base of N=3x106 cycles. Analysis of surface residual stresses shows that after non-abrasive ultrasonic finishing in the selected mode, predominantly compressive residual stresses are formed on the surface, reaching 245 MPa. Fatigue tests have shown that the processing of commercially pure titanium in the ultrafine-grained state by the method of non-abrasive ultrasonic finishing leads to an increase in the fatigue limit by up to 20%. So, on the selected test base, the endurance limit of UFG specimens (diameter 10 mm, groove 2.5 mm deep with R=2 mm and an angle of 80 °) with non-abrasive ultrasonic finishing reaches σ-1= 490 MPa, and without treatment σ-1= 400 MPa.
