ABSTRACT:
A method of preparation of a ternary or quaternary alloy composed of the elements A.sup.1 A.sup.2 A.sup.3 (ternary alloy) or the elements A.sup.1 A.sup.2 A.sup.3 A.sup.4 (quaternary alloy) consists of the successive steps of preparation of one or a number of binary alloys such as A.sup.1 A.sup.2, purification of the binary alloys by zone melting, placing of the binary alloy or alloys which are in the solid state together with the other constituent elements of the alloy within a container in the presence of a solvent, crystallization of the ternary or quaternary alloy by melting all the elements within the container and recrystallization in the presence of the solvent.
