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 ΔTx of a supercooled liquid as expressed by ΔTx=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.
Claims12
A sinter comprising a high-hardness glassy alloy containing at least Fe and at least a metalloid element and having a temperature interval ΔTx of a supercooled liquid as expressed by ΔTx=Tx−Tg, where, Tx is a crystallization temperature and Tg is a glass transition temperature of at least 20° C.
- wherein said glassy alloy mainly comprises at least one element selected from the group consisting of Fe, Co and Ni and contains at least one selected from the group consisting of Zr, Nb, Ta, Hf, Mo, Ti and V.
