METHOD FOR SINGLE-STEP HEAT TREATMENT OF TITANIUM ALLOYS, GOLF CLUB STRIKING FACES, AND GOLF CLUB HEADS

Abstract: a method for manufacturing a golf club head includes forming a pre-forged striking face insert from an �-� titanium alloy having a molybdenum equivalency of about 6 to 12 or an al equivalency of about 2 to 7, and forging the pre-forged striking face insert into a forged striking face insert having a specified geometry or curvature. in some embodiments, the method may also include performing only a single-step heat treatment on the striking face insert including heating the striking face insert to a temperature below a beta transus temperature of the �-� titanium alloy for a period of time, and thereafter cooling the striking face insert to ambient temperature. in some other embodiments, the method may further include attaching the forged striking face insert to an aft body portion to form a golf club head, and performing the single-step heat treatment and cooling on the golf club head.
