提出了椭球模型, 在不计晶界影响的条件下, 用来模拟高碳、高镍钢内竹叶状马氏体生长动力学。引用文献<参考文献原文>通过试验测得的马氏体超声速生长速度G约为1 000 m/s的数据, 模拟了马氏体生长动力学。结果表明: 和一般的金属中的低速生长相变动力学情况一样, 马氏体的相变是以成核和长大方式进行的。引用文献<参考文献原文>通过试验测得的高镍钢在低温恒温下竹叶状马氏体生长动力学数据, 寻求竹叶状马氏体的成核速率N·和生长速度G。利用上述的N·和G, 模拟竹叶状马氏体生长动力学。将所获的模拟图像与文献<参考文献原文>中由试验获得的有关高镍钢的真实竹叶状马氏体图像比较表明: 其结果与预期一致, 令人满意。

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.
