摘要
Disclosed is a titanium alloy fine wire that has a diameter of 10 to 200 μm and has a fine acicular structure. The titanium alloy fine wire is manufactured by a molten metal extraction method that uses an α-β-type titanium alloy such as Ti-6Al-4V as a titanium material and brings a target wire diameter to 10 to 200 μm. In this case, the repetition of an annealing step required of the conventional technique is unnecessary. Accordingly, the titanium alloy fine wire can be manufactured at low cost. In particular, a fine acicular structure composed mainly of an α’ phase (hexagonal martensite) is obtained during rapid cooling in the manufacture of the fine wire. Since the martensite is included as a main structure of a fine acicular structure in the titanium alloy fire wire, the strength can be further improved. Further, the occurrence of fatigue cracking can be prevented to further improve the fatigue strength.
