Shot Peening of a Titanium Alloy for Medical Implant Applications with Ziirconia Shot
Shot peening with steel shot followed by a cleaning process with glass beads is commonly used as surface finish in the production of modular hip endoprostheses. The induced compressive residual stresses increase the resistance against fatigue and fretting fatigue. The surface roughness can be adjusted in a range that enhances the physiological acceptance I compatibility of monolithic ~rnplants....
متن کاملStudy and Simulation of Shot peening Effect on Fatigue Life of a Powder Forged Connecting rod
Shot peening applies a residual compressive stress field (RCSF) on the surface of parts. It also shifts “crack nucleation sites” to sub-surface locations. A nondestructive method of measuring the stresses, Sin2ψ was utilized here and the stress values introduced to Ansys software. For this purpose, uniform stress in all directions was applied on the con rod. Loading on the rod in Ansys had thre...
متن کاملEvolution of magnetization reversal mechanism in Fe-Cr alloy films
A large thin film sample of FexCr1−x alloy with a composition gradient x=0.38−0.52 has been prepared by co-sputtering to investigate magnetic anisotropy and magnetization effects on reversal mechanisms. The single-phased Fe-Cr films have a bcc structure with 110 preferred orientation. Since the magnetization decreases as the Fe content is decreased and the uniaxial anisotropy energy keeps at al...
متن کاملVibrational properties of alpha- and sigma-phase Fe-Cr alloy.
Experimental and theoretical studies, of the Fe-partial phonon density of states (PDOS) for Fe52.5Cr47.5 alloy having alpha and sigma phases were carried out. The former using the nuclear resonant inelastic x-ray scattering method, and the latter with the direct one. Characteristic features of PDOS, which distinguish one phase from the other, were revealed and successfully reproduced by the the...
متن کاملSide Effects of Shot Peening on Fatigue Crack Initiation Life
Shot peening beneficial effects on fatigue life of mechanical components are well known. However, there are some reports in the literature that indicate inappropriate shot peening parameters tend to reduce the fatigue life. It is therefore, the purpose of this study to find a logical quantitative justification for these observations. Using finite element method, a dynamic elastic-plastic simula...
