ABSTRACT:
The present invention relates to a sinter and a casting comprising a high-hardness glassy alloy containing at least Fe and at least a metalloid element and having a temperature interval .DELTA.Tx of a supercooled liquid as expressed by .DELTA.Tx=Tx-Tg (where, Tx is a crystallization temperature and Tg is a glass transition temperature) of at least 20.degree. C., which permit easy achievement of a complicated concave/convex shape.
