Sinter and casting comprising Fe-based high-hardness glassy alloy

摘要

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 DELTATx of a supercooled liquid as expressed by DELTATx=Tx-Tg (where, Tx is a crystallization temperature and Tg is a glass transition temperature) of at least 20° C., which permit easy achievement of a complicated concave/convex shape.
