摘要： PROBLEM TO BE SOLVED: To provide a titanium alloy which has high strength and low Young's modulus, is easily cold workable, is light in weight, and is appropriate for spectacle frames, artificial bones, etc., and its production method.
SOLUTION: The alloy unstable in a β phase at ordinary temperature is cold worked to generate a martensite phase and is thereafter subjected to heat treatment of 150 to 350°C, and thereby the high strength, low Young's modulus titanium alloy composed of the fine β phase generated by reverse transformation and the fine α phase deposited within the β phase is obtained. Also, the alloy having a martensite structure is enhanced in the orientability of the martensite by working, and thereby the high strength, low Young's modulus titanium alloy is obtained. The alloy composition includes one or more kind selected from V, Mo, Nb, Ta and W at 5 to 40 wt.% and contains one or more kind from Al, Sn, and Zr at ≤10 wt.% and consists of the balance Ti and impurities.
