ABSTRACT:
New copper-rich metal alloys containing nickel along with certain specific amounts of boron are disclosed. The alloys are subjected to a rapid solidification processing (RSP) technique which produces cooling rates between .about.10.sup.5.degree. to 10.sup.7 .degree. C./sec. The asquenched ribbon, powder, etc. consists primarily of a metastable crystalline solid solution phase. The metastable crystalline phases are subjected to suitable heat treatments so as to produce a transformation to a stable multiphase microstructure, which includes borides. This heat treated alloy exhibits superior mechanical properties with good corrosion and/or oxidation resistance for numerous engineering applications.
