Literature Data

The only published work on the Ag-Au-Pt system is due to [1958Nov] who studied 33 alloys at 10 mass% composition intervals up to and including 60 mass% Pt. Thermal analysis on cooling was relied on to provide data on transformations involving the liquid phase. All alloys were heat treated at 900°C for 6 h and 600°C for 18 h, water quenched and examined metallographically in addition to determination of their hardness, electrical resistance, temperature coefficient of electrical resistance and thermoelectric power. All alloys were similarly studied in the annealed condition, to represent room temperature equilibria, but it is not clear what heat treatment was used to define the annealed state. 22 alloys were mechanically tested, for strength and ductility, in the annealed condition. [1958Nov] used 99.99% Au, refined Pt o...
