GOLF CLUB HEAD WITH IMPROVED PERFORMANCE

摘要

A golf club head with an improved striking face is disclosed herein. More specifically, the present invention utilizes an innovative die quenching method that can alter the Young's modulus of the material of the striking face. The striking face portion of the present invention generally created from an α+β titanium alloy such as SP 700 that contains a β rich alloy composition to create more phase change in the alloying elements. In a preferred embodiment, the die quenching process could create a localized change in the material's Young's modulus throughout different regions of the striking face, resulting in a change in the Young's modulus of the material within the same striking face.

主权项

1. A golf club head comprising:
a striking face portion; and an aft portion, attached to a rear of said striking face portion; wherein said striking face portion is made out of an α−β titanium alloy comprising at least one of a body centered cubic β titanium allow; and wherein at least a portion of said striking face portion has a Young's modulus of less than about 80 GPa.
