Computer Investigations on Phase Decomposition in Real Alloy Systems Based on a Discrete Type Phase Field Method

Abstract

ABSTRACTOn the basis of the discrete phase field method where the difference expression of non-linear kinetic equation, the composition dependencies of the atomic interchange energy and the inhomogeneous elasticity are taken into consideration so as to be applicable for the real alloy system. The phase decomposition and the microstructure formation are computer simulated for the Fe-Al- Co ternary ordering alloy by utilizing the thermodynamic data.
