Macro-fiber process for manufacturing a face for a metal wood golf club

Abstract

A near-net shape titanium club face for a metal wood golf head is manufacturing with improved product structure and performance. More specifically, the invention provides a metal wood golf club head face consisting of layers of grain fibering by controllable grain flow along face-orientation and surface contours, similar to composite structures, for improved directional strength, impact strength and toughness, as well as hitting face thickness design flexibility for improved hitting sound and increased coefficient of restitution without sacrificing face performance and durability. The hitting face is made by precision hot-die forging in closed dies through large (α+β) forge deformation to net or near-net shape from a β-treated work piece. Alternatively, the process may be applied to aluminum alloys or steels.
