Martensite Transformation Kinetic and Simulation by Stereo Image

The separated nucleation and continue growth model has been suggested for ellipse ball martensite.Two marteresite transformation kinetic formulas for separated nucleation and continue growth were derived.According the calculated data from transformation kinetic formulas and the Ansys software were used to display martensite transformation kinetic by stereo image.It was as same as expected that martensite as bamboo leaf obtained from experiment.Comparing the statistical average for martensite fraction of per area AS and the statistical average for martensite number per area NAS at random section with the martensite fraction mathematical expectation AE and the marteesite number mathematical expectation NAE .It was showed that there were some error between both of them,which was caused by the shape of martensite and the less samples.
