Abstract: The Ti-6Al-4V alloy is currently utilized as structural materials in artificial hip and knee joints, bone plates and screws, and artificial dental roots. It is mainly used in implants that replace hard tissue because has a high strength, good corrosion resistance, high biocompatibility compared to other conventional metallic biomaterials such as stainless steel and Co-Cr-Mo alloys. The Ti-6Al-4V alloy with low Young’s modulus equivalent to that of the cortical bone is a simultaneously required in order to inhibit bone absorption. By short-time solution treatment and subsequent short-time aging, the mechanical properties of Ti–6Al–4V alloy can be improved while maintaining a low Young’s modulus. The results shown that optimum heat treatments obtained in the alloys conducted the short-time solution treatment at 930 ^oC (1203 K) for 60 s and subsequent short-time aging at 530 ^oC (803 K) for 40 s. It was obtained the yield strength and tensile strength improved without reduction in ductility. Their maximum improvement rates of reached 21,6% and 21,1%, respectively and the Young’s modulus reduced with maximum rates of reached 19%.
