【摘要】 <正> Based on the theoretical treatment in Part I, short range order (SRO) formation under the influence of qenched-in vacancy is experimentally investigated by measuring the change of SRO-induced resistivity in Au50%Pd. By using the method introduced in this work information about the kinetics of SRO formation and the behaviour of vacancy annihilation in alloy can be gained and the complete set of diffusion data including the formation energy of vacancy and the activation energy for self-diffusion of components in alloy can be determined.
