PURPOSE: To produce an Fe-base metallic glass alloy in which the temp. interval between the crystallization starting temp. and the glass transition temp. in a supercooled liq. is specified. CONSTITUTION: An Fe-base alloy in which the temp. interval of a supercooled liq. expressed by the formula ofΔTx=Tx-Tg (Tx denotes the crystallization starting temp. and Tg denotes the glass transition temp.) is regulated to >=40K is prepd. This Fe-base alloy contains Fe, the other metals and semimetals. As the semimetals, at least one or more kinds among P, C, B and Ge are used, and as the other metals, at least one or more kinds among metallic elements (Al, Ga, In and Sn) in the groups IIIB and IVB are used. Thus, the Fe-base metallic glass alloy obtd. as a bulky alloy extremely ticker than the conventional amorphous alloy thin strip and having excellent magnetic properties can be produced.
