TITANIUM ALLOY MEMBER AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a titanium alloy member superior in durability, and to provide a manufacturing method therefor. SOLUTION: The titanium alloy member has a compression stress of 270 MPa or higher within about 100μm deep of the surface. The titanium alloy member shows high fatigue strength because of high compressive stress imparted in the vicinity of the surface. COPYRIGHT: (C)2006,JPO&NCIPI
