Ranjan Ray, Viswanathan Panchanathan: Cobalt-chromium alloys which contain carbon and have been processed by rapid solidification process and method. Marko Materials, August 23, 1983: US04400212 (1 worldwide citation)

New cobalt base alloys containing chromium and carbon are disclosed. The alloys are subjected to rapid solidification processing (RSP) technique which produces cooling rates between 10.sup.5 to 10.sup.7 oC/sec. The as-quenched ribbon, powder etc. consists predominantly of amorphous phase. The amorph ...
