PROBLEM TO BE SOLVED: To provide a lightweight titanium alloy low in a Young's modulus, easily subjected to cold working, and suitable for a spectacles frame or the like, and to provide a method of producing the same. SOLUTION: The low Young's modulusβtype titanium alloy comprises, by atom, 13 to 28% Nb and 0.1 to 10% Sn, and the balance Ti with impurities. Alternatively, the low Young's modulusβtype titanium alloy comprises, in addition to the components, each 0.1 to 5% of one or more kinds of metals selected from V, Mo, W, Zr and Al, and the balance Ti with impurities. Each alloy is worked, is thereafter heated to aβtransformation point or higher and is cooled so as to be aβalloy. COPYRIGHT: (C)2005,JPO&NCIPI
