Abstract:
A method of manufacturing a metal wood golf club head, comprising the steps of: heating a metal workpiece to above the &bgr;t temperature of the workpiece thereby creating a &bgr;-preform grain structure therein; heating a set of forming dies to a temperature above &bgr;tâˆ’400Â° C., for enabling uniform plastic grain flow in the workpiece; heating a forge to a temperature below the &bgr;t temperature of the workpiece; and forging the workpiece in the forge to one of a net shape and a near net shape using the forming dies with a closed die (&agr;+&bgr;) finish forging technique, whereby the workpiece achieves a macro-fiber grain flow.
