Literature Data

[1970Mas] examined a total of 42 ternary alloys along the 12.2, 13.7 and 15.2 at.% Sn sections. Alloys were prepared from >99.99% pure elements by melting under He in silica tubing, homogenized for 14 d under He at temperatures ranging from 275 to 550°C and analyzed by X-ray powder diffraction at 30°C after quenching from the homogenizing temperature. All the alloys had the hcp ζ phase indicating the presence of a continuous solid solution between the ζ phases of the Ag-Sn and Au-Sn systems for temperatures above 275°C. [1971Eva] and [1974Eva] used only thermal analysis techniques to outline the ternary equilibria for alloys containing >20 at.% Sn. Ag and Au of purity >99.999% and >99.99% Sn were used to prepare alloys which were thermally analyzed at heating and cooling rates of 2 to 5 K•min...
