Effect of lattice mismatch-induced strains on coupled diffusive and displacive phase transformations
, 2006 Materials which can undergo slow diffusive transformations as well as fast displacive transformations are studied using the phase-field method. The model captures the essential features of the time-temperature-transformation (TTT) diagrams, continuous ...
