PROBLEM TO BE SOLVED: To provide a near-β type titanium alloy which is excellent in tensile strength and elongation, and also has excellent low cycle fatigue properties.;SOLUTION: In the near-β type titanium alloy, Mo equivalent obtained from formula of [Mo]+[Ta]/5+[Nb]/3.5+[W]/2.5+[V]/1.5+1.25[Cr]+1.25[Ni]+1.7[Mn]+1.7[Co]+2.5[Fe] is 5 to 10%, the average area ratio of a primary αphase occupied in a metallic structure is 40 to 52%, further, the average aspect ratio of the primary α phase is 3, 3 to 5.0, and the average maximum major axis is 25 to 40 μm.;COPYRIGHT: (C)2011,JPO&INPIT
