PCT No. PCT/JP95/01817 Sec. 371 Date Jun. 2, 1998 Sec. 102(e) Date Jun. 2, 1998 PCT Filed Sep. 13, 1995 PCT Pub. No. WO97/10066 PCT Pub. Date Mar. 20, 1997A method for producing titanium alloy turbine blades comprising the steps of (a) forming turbine blades of titanium alloy through hot forging or machining, (b) cooling leading edges on tip portions of the turbine blades including covers thereof formed through hot forging or machining faster than blade main body after final hot forging or solid solution treatment, and (c) heat treating the cooled turbine blades. With this method, it is possible to manufacture titanium turbine blades in an economical fashion and obtain titanium alloy turbine blades superior in reliability by preventing erosion.
