Abstract

Studies on the phase constitution of annealed master ingots of the Au(49)Ag(5.5)Pd(2.3)Cu(26.9)Si(16.3) alloy suggest that it is a quinary eutectic and revealed which phases solidify from the melt. The alloy has been amorphized in ribbon form. Ribbon crystallization has been studied in isothermal and continuous heating modes. From such experiments data on the mechanism and kinetics of crystallization have been obtained. Time-temperature-transformation and Continuous Heating Transformations plots for crystallization have been derived from thermal data.
