To produce an alloy having extremely homogeneous distribution of alloy components by successively stacking plural alloy components having different melting points in the order of their ascending melting point in a cold-walled crucible and then adding a heat energy to the stacked alloy components to melt.
The objective alloy is produced by stacking alloy components in a cold-walled crucible having a water-cooling wall 2 and a cooled crucible base 3 in the order of their ascending melting point, e.g. in the following order: an alloy component A (e.g. Al) having the lowest melting point, an alloy component B(e.g. Ti) having the second lowest melting point, an alloy component C(e.g. Cr) having the third lowest melting point B, and an alloy component D(e.g. Nb) having the highest melting point, and then heating the stacked alloy components to melt successively the alloy components A, B, C and D, using an induction coil 4. By this process, the alloy having an exact chemical composition can be obtained.
