SOLID SOLUTIONS IN GOLD-COBALT AND COPPER-COBALT ALLOYS

Abstract

By quenching liquid alloys, single-phase solid solutions are obtained between 0 and 42 at. % cobalt in gold and between 0 and 15 and 75 and 100 at. % cobalt in copper. Metastable solid solutions are also found in multi-phase alloys between 42.0 and 49.0 and between 69.0 and 100 at. % cobalt in gold. The nability to achieve complete solid solubility in gold-cobalt and copper-cobalt alloys is rationalized by considering the rate processes during cooling and solidification. Trends in lattice distortion and shifts in the compositions of the meltingpoint minima and critical points are discussed for the binary alloys of copper, silver and gold with some of the transition metals of the first period.
