摘要

The present invention is a process for producing a rare earth alloy including heating a raw material alloy which is compounded so as to have a composition represented by the formula: A3-xBXC (wherein A and B each is at least one member selected from transition metals consisting of Fe, Co, Ni, Ti, V, Cr, Zr, Hf, Nb, Mo, Ta and W, and C is at least one member selected from Group 13 or 14 elements consisting of Al, Ga, In, Si, Ge and Sn) to be a molten ally, and quench-solidifying the molten alloy at a cooling rate of 1 x 10<2> to 1 x 10<3> °C/sec.
