| 摘 要： | 马氏体相变是改善钢铁材料力学性能的1种重要途径。本文考虑了晶粒的随机分布(即细观各项异性),在0-1相变模型的基础上,采用热弹塑性有限单元法,以45#细长钢棒的淬火处理为例,进行了变温马氏体相变的数值模拟。

| Abstract: | Martensitic transformation is one of the important means to improve the properties of steel and iron.In this paper,in consideration of the random distributions of the grains(the anisotropy microstructure),on the basis of 0-1 phase transformed model,by using thermal elastic and plastic finite element method,taking quenching treatment of a 45# thin,long,steel bar for example,we conducted on the simulation of the temperatur-changed martensitic transformation. |
