L12-long-range order in Cu3Au: kinetics and equilibrium as studied by residual resistivity

The evolution of L12-long-range order in Cu3Au was studied as a function of temperature by means of residual resistivity measurement. Kinetics as well as temperature dependence of equilibrium values of the LRO-parameter were studied during isothermal annealing and the LRO-equilibrium values obtained were compared with model calculations and X-ray diffraction measurements. Comparing the analyses of order-order relaxations with those of disorder–order relaxations, information is gained on the growth kinetics of ordered antiphase domains.
