Abstract: A golf club is made of a club shaft and a club head. Either the club shaft or the club head is made at least in part of a in-situ composite of bulk-solidifying amorphous alloy. The weights of the various club heads of a set, which have different volumes, may be established by varying the compositions and thence the densities of the bulk-solidifying amorphous alloys.

Abstract: A method of investment casting bulk-solidifying amorphous alloys, and the formation of articles of bulk-solidifying amorphous alloys made by such methods are provided.

Abstract: A process and apparatus for thermoplastic casting of a suitable glass forming alloy is provided. The method and apparatus comprising thermoplastically casting the alloy in either a continuous or batch process by maintaining the alloy at a temperature in a thermoplastic zone, which is below a temperature, Tnose, (where, the resistance to crystallization is minimum) and above the glass transition temperature, Tg, during the shaping or moulding step, followed by a quenching step where the item is cooled to the ambient temperature. A product formed according to the thermoplastic casting process is also provided.
