Abstract
A cold-worked titanium material subjected to isostatic material and a backing plate are brought into contact with each other and subsequently hot-pressing. By such working the titanium material and the backing plate are bonded with each other by mutual diffusion and simultaneously the titanium material is recrystallized. The isostatic pressing is performed under a pressure of 50 to 200 MPa at a temperature of 300.degree. to 450.degree. C. The surface of the titanium material is preferably subjected to a surface roughening treatment to provide with a roughness level of 6S to 12S prior to the isostatic pressing.
