Atomic mobilities and diffusion characteristics for fcc Cu–Ag–Au alloys

Abstract: CALPHAD kinetics has evolved to be a well-established discipline, which allows complex non-equilibrium processes to be fully explored. Such a success relies on the use of Redlich–Kister polynomials to describe atomic mobilities, with the effect of temperature, composition, magnetic ordering and chemical ordering sufficiently taken into consideration. There is thus an increasing demand to construct high-quality atomic mobility databases for alloys of interest. Based on the CALPHAD framework, the atomic mobilities in fcc Cu–Ag–Au alloys are reported in this work, the results of which can provide fruitful information on alloy design. [Copyright &y& Elsevier]
