Experiment-based analyses of martensitic transformation plasticity predictions from different models in cases of pre-hardening and gradually varying loads

摘要

Different types of modelling - analytical, numerical, diffusive-like, displacive - dedicated to prediction of transformation plasticity (TRIP) are investigated at the lights of experimental tests of martensitic transformation performed for different types of uniaxial loads: pre-hardening, increasing/decreasing/constant load imposed during the transformation. Conclusions are then drawn on the relevance of each type of modelling for predicting TRIP according to the loading history.
