摘要：

A wide range of novel multicomponent amorphous alloys can be manufactured by the new method of equiatomic alloy substitution for the early and late transition metal contents of Zr-based amorphous alloys. Amorphous alloys are formed by melt spinning in the alloy system A(x)-B90-xAl10 over the composition range x=20-70at% when the early transition metal A=Ti33Zr33Hf33 and the late transition metal B=Ni50Cu50. Amorphous alloys are also formed over the composition range x=50-70at%, when the early transition metal content is extended to A=Ti25Zr25Hf25Nb25, or when the late transition metal content is extended to B= Ni33Cu33Ag33. The most stable amorphous alloy of these is (Ti33Zr33Hf33)(40)(Ni50Cu50)(50)Al-10 with a crystallisation temperature of T,= 545 'C. The amorphous alloy with the largest supercooled liquid region is (Ti33Zr33Hf33)(50)(Ni-33,Cu33Ag33)(40)Al-10 with a crystallisation-glass transition temperature difference of T-x -T-g= 103 degreesC.
