Figure 9 The first SANS measurements on alloys to be compared directly with simulation. The series shows the variation with both time and temperature.
Windsor's interest in computer modelling lead to him taking up the new home micros directly they came out in 1981[120]. His little book, "Four Computer Models" [100] showed Monte Carlo modelling in action and fellows may remember him at the 1985 soiree. His programs grew into three dimensions, into face centred cubic lattices, and to displays which could show the evolution of any one cluster from its nucleation as a random cluster to the final equilibrium state. This paper was written following a series of commercial experiments for Alan Bowen at RAE Farnborough to measure the evolution of the microstructure as a function of time and temperature. The material was grown by evaporation of the alloy elements onto a cooled substrate, by-passing the limitations of the phase diagram. It lead to the novel properties which have been explored in several papers [133,142]
