ABSTRACT:
A process for casting molten transition metal alloy comprising 15 to 35 at % of rare earth metal in which the molten alloy is contacted with a surface (26) of a backing member (25) and the alloy is caused to solidify while in contact with the surface (26) such that when the alloy has solidified there is produced a unitary structure (21) comprising a solid layer (27) of the alloy bonded to the backing member (25). The process minimizes the effects of cracking in the alloy and facilitates the use of the alloy as a sputter target.
