Combined Effect of Cryogenic and Aging treatments on Wear Behavior of Ti-6Al-4V α/β Alloy for Biomedical Applications

Ti-6Al-4V α/β titanium alloy is used in biomedical applications to produce artificial joints due its excellent osseointegration property, high corrosion resistance, low density, and Elasticity modulus compatible with bone structure. Considering the usage area, expected have tensile properties wear resistance. In this study, aging treatment a combination of cryogenic were applied obtain Cryogenic was conducted at deep (-196°C) shallow (-140°C) temperatures. Also, with/without as single-step or duplex. The effect heat types on alloy's mechanical microstructural determined by test, hardness XRD phase analysis, investigations. With application duplex amount β phases decreased, good balance between strength elongation obtained, resistance increased compared aging. addition, decrease temperature slowed down transformation kinetics caused precipitation α both aged samples. Superior obtained reduction microstructure samples that after treatment.
