PHASE FIELD SIMULATION OF MICROSTRUCTURE EVOLUTION IN THERMAL AGING OF CAST AUSTENITIC STAINLESS STEELS

摘要：

The spinodal decomposition of the ferritic Fe-Cr solid solution leads to a fluctuation of the Cr concentration corresponding to the formation of an interconnected sponge-like network of the Cr-enriched αdomain. In the present work, the morphological evolution during spinodal decomposition in Fe-Cr ferritic solution was studied. A Fourier transformation method was used to solve the Cahn-Hilliard diffusion equation. We demonstrated the effect of the aging time and temperature on morphological change during the microstructure evolution.
