ABSTRACT:
A first method for producing a half Heuslar alloy includes quench-solidifying a molten alloy at a cooling rate of 1×102to 1×103° C./sec to produce a half Heuslar alloy having a ratio of strongest peak of the half Heuslar phase of 90% or more in an as-cast state, the alloy having the formula: ABC (wherein A and B each is at least one member selected from Fe, Co, Ni, Ti, V, Cr, Zr, Hf, Nb, Mo, Ta and W, and C is at least one member selected from Al, Ga, In, Si, Ge and Sn). A second method is one in which the half Hueslar alloy has the formula: Ti1-xAxNi1-yBySn1-zCz(wherein each of A and B is at least one member selected from Co, Ni, Ti, V, Cr, Zr, Hf, Nb, Mo, Ta and W, C is at least one selected from Al, Ga, In, Si, Ge and Sn).
