内容記述 | Secondary ion mass spectroscopy (SIMS) was used to measure the diffusion coefficients and isotope effects of zinc in the Cu3Au alloy in various temperatures across L12-type order-disorder transition one. The temperature dependence of diffusion coefficient is not explained by a simple activation process of Arrhenius type because of the order-disorder transition. The activation energy Q and pre-exponential factor D0 for diffusion were Q = 126(1-0.70S+0.65S2) kJ/mol D0= 1.04×10-5cm2/sec, where S is a long-range order parameter. The isotope effect remained about 0.5 in the disordered region, while it increased with decreasing temperature in the ordered region. | |||||
