Abstract:

A method of preparing alloy of a transition metal and lanthanide comprising the steps of alloying a transition metal, boron, at least one lower-weight lanthanide having none or few stable compounds with iron, optionally one or more higher-weight lanthanides, a glass former, and optionally the pseudo lanthanide, yttrium, forming an amorphous or nearly amorphous metastable microstructure in the alloy and heating the amorphous alloy to form a polycrystalline, multiphase, fine-grain single domain structure.
