Martensitic transformation under impact with high strain rate

This paper deals with the quantitative prediction of the volume fraction of martensitic transformation in a austenitic steel that undergoes impact wit h high strain rate. The coupling relations between strain, stress, strain r ate, transformation rate and transformed fraction were derived from the OTC model and modified Bodner-Partom equations, where the impact process was c onsidered as an adiabatic and no entropy-increased process (pressure less t han or equal to 20GPa). The one-dimensional results were found to model and predict various experimental results obtained on 304 stainless steel under impact with high strain rate. (C) 2001 Published by Elsevier Science Ltd.
