<p><P>PROBLEM TO BE SOLVED: To provide: titanium alloy billets with which anα+βtype titanium alloy product with small anisotropy can be manufactured at a relatively simplified forging process; a method for producing the titanium alloy billets; and a method for producing a titanium alloy forged material, by which a titanium alloy forged material is produced using the titanium alloy billets. <P>SOLUTION: In the titanium alloy billets, a c-axis direction of anαphase is integrated within±30°from the longitudinal direction of each of the titanium alloy billets toward the Y direction (direction of heavy reduction) and in a range±40-90°from the longitudinal direction of each of the titanium alloy billets toward the X direction (direction perpendicular to the Y direction and the longitudinal direction), and a degree of the integration is 3 or greater. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
