High-cycle fatigue properties of an easily hot-workable (α+β)-type titanium alloy butt joint prepared by friction stir welding below β transus temperature
TL;DR: In this paper, friction stir welding was applied to a butt joint between the 2-mm-thick plates of an (α+β)-type titanium alloy with high hot workability, Ti-4.5Al-2.5Cr-1.2Fe-0.1C alloy (Ti531C), to obtain defect-free welds.
Journal ArticleDOI
Formation of L10-type ordered β′ phase in as-solutionized dental Ag–Pd–Au–Cu alloys and hardening behavior
TL;DR: In this article, the relationship between the microstrucutural changes of L1 0 -type ordered β′ phase and hardening behavior in as-solutionized dental Ag-Pd-Au-Cu alloys was investigated by changing the cooling rate and the solution treatment temperature.
Journal ArticleDOI
Enhancing the durability of spinal implant fixture applications made of Ti-6Al-4V ELI by means of cavitation peening
TL;DR: In this paper, the surface treatment technique known as "cavitation peening" was employed in order to enhance the durability of spinal implant fixture applications, which are subject to fretting fatigue.
