Abstract
A golf club which has a clubface of desired shape comprising an alloy metal is provided. The golf club has excellent strength properties as well as excellent ball hitting properties. The clubface is free from casting defects such as cold shuts, and preferably, free from the crystalline phase formed from crystal nuclei through nonuniform nucleation since the club face is produced in a simple, highly reproducible, one-step process by selectively cooling the molten metal at a temperature above the melting point at a rate higher than the critical cooling rate, and the product comprises a single amorphous phase. The metallic glass face used in the golf club is produced by filling a metal material in a hearth; melting said metal material by using a high-energy heat source which is capable of melting said the metal material; pressing said the molten metal at a temperature above the melting point of said the metal material to deform the molten metal into the desired shape by at least one of compressive stress and shear stress at a temperature above the melting point, while avoiding the surfaces of the molten metal cooled to a temperature below the melting point of said the metal material f…
