Effect of excess Au on antiphase domain growth in Cu < inf> 3 Au
The kinetics of antiphase domain growth have been studied in three nonstoichiometric Cu3Au alloys containing nominally 26, 28, and 31.5 at. pct Au. During isothermal annealing of disordered samples below the critical temperatures, the domain growth in all of the alloys initially followed the same t 1/2 dependence found previously for stoichiometric Cu3Au. At long times, the two alloys furthest off stoichiometry reached limiting domain sizes which decreased with increasing Au content. Although the role of the excess Au in determining these limiting sizes is not clear, it is evident that most of the excess Au is accommodated within the domains. The antiphase domain size distributions in the alloys agree with those found for the stoichiometric alloy. © 1975 The Minerals, Metals & Materials Society - ASM International - The Materials Information Society.
