| 摘 要： | 焊接热影响区是影响焊接性能的主要区域。焊接热影响区的晶粒长大常常导致焊接热影响区成为性能薄弱的环节，对焊接热影响区晶粒长大的研究一直是焊接接头的重要研究课题。焊接热影响区微观结构演化与诸多因素密切相关，是一个复杂的过程。运用适当的计算机方法进行模拟，完成对晶粒生长的完全预测，具有重要的意义，可以为优化焊接工艺参数，提高焊接质量提供依据。在此对在模拟焊接热影响区微观结构的演化时采用的基本方法进行综述。

| Abstract: | The heat affected zone(HAZ)is one of the main areas which affect the properties of welds.The grain growth in HAZ often makes it to be a weak part of a weld and the research work on the grain growth in HAZ of welds is always an important topic for a weld.The microstructure evolution in HAZ of Welds is a complex procedure,which associates with many factors.It is essential meaningful to complete the prediction of grain growth simulated by computer using proper methods and that can provide an new and important foundation for optimizing welding parameters and improving the quality of welds.This paper introduces the basic methods for simulating the microstructure evolution in HAZ of Welds. |
