Abstract

A metastable shift of the solubility limit was produced by splat-quenching in Sn-Bi alloys containing 15, 20 and 25 at. % bismuth. Decomposition of the supersaturated a phase was investigated in the temperature range −40 to O° C. An activation energy of 39.8±3.0 kJ mol−1 was obtained for the decomposition of Sn-25 at. % Bi. Splat-quenched Cu-Sb alloys with different compositions were also studied. The decomposition of the retainedβ high-temperature phase was followed at 200 and 330° C. Neither an increase of solubility of copper into antimony nor new phases at the eutectic composition were observed in quenched foils.
