Martensite Transformation Kinetic and Simulation of Image

The ellipse ball model has been suggested to simulate bamboo leaf Martensite phase transformation kinetic in high carbon and high nickel steel under the condition without considering the effect of boundary. Using the data for Martensite ultrasonic growth rate G about 1 000 m/s obtained from experiment in literature <参考文献原文> to simulate Martensite phase transformation kinetic by computer, the results of simulation showed that it was as same as ordinary for low growth rate phase transformation kinetic in metal. The high growth rate Martensite phase transformation kinetic was also performed by means of nucleation and growth. Using the data for high nickel steel at low temperature isothermal Martensite transformation kinetic obtained from experiment in literature <参考文献原文>, to find the nucleation rate N· and growth rate G for bamboo leaf Martensite. Using N· and G mentioned above to simulate bamboo leaf Martensite transformation kinetic by computer and compare with the image for real bamboo leaf Martensite for high nickel steel obtained from experiment in literature <参考文献原文> showed that the results were as well as predicted also.
