摘要：

A simple Monte Carlo model has been used to simulate diffusional phase transformations occurring in binary alloys during thermal ageing. The results of the simulation are compared directly with atomic-scale chemical information obtained from position-sensitive atom probe microanalysis. A simple pair potential model is found to give a good match with the ageing behaviour of spindodally decomposing iron-chromium alloys. Initial results on the modelling of nucleation and growth are presented, and compared with phase separation of copper-cobalt alloys.
