Method of manufacturing high strength titanium alloy golf club head member and golf club head member

摘要

A method for manufacturing a high-strength titanium alloy golf club head part includes making at least one golf club head part with a titanium alloy. The golf club head part is then heated to a temperature higher than a critical temperature of generating martensite and maintained above the critical temperature not more than thirty minutes. The golf club head part is then cooled to a temperature below the critical temperature at a cooling rate higher than 10° C./s. Next, the golf club head part is heated to a heat-treatment temperature higher than 450° C. and maintained at the heat-treatment temperature at least one hour. The golf club head part is then cooled to room temperature. The mechanical characteristics of a golf club head formed by the golf club head part are enhanced.
