Abstract

Small amounts of liquid alloys are cooled to the solid state very rapidly by means of a technique which is described in detail. Procedures for studying the resultant thin, irregular foils are discussed; most of the results are obtained from x-ray diffraction experiments. Among the nonequilibrium structures found in various alloys are cited the metastable solid solutions in silver-copper and gallium antimonide-germanium alloys, the extended primary solid solutions in some silver-base alloys, and the metastable hexagonal close-packed structures in silver-germanium alloys. The quenching technique is discussed and tentative criteria for the prediction and rationalization of certain metastable structures in alloy systems are inferred from an analysis of the process.
