Phase Transformations in Ag48Zn5oAu2 and Ag48Zn5oCu2 Alloys

Abstract

The order-disorder phase transformation temperatures for Ag48Zn50Au2 and Ag48Zn50Cu2 alloys have been determined using resistivity techniques and the ordering energies of the closest neighbors of the AuZn and AgCu pairs calculated. Investigation of the kinetics of the β′ → ζ0 phase transformation using resistivity, metallographic, microanalytical, and x-ray techniques showed a two-phase field in both alloys, corresponding to the β + ζ0 phases.
