在前面的工作中,我们开发了一种用于单晶焊缝中晶体生长和组织发展的矢量化分析技术。基于矢量化方法,采用数值模拟和实验观测相结合的方法,对CMSX-4单晶高温合金激光表面重熔过程中的晶体生长和杂散颗粒分布进行了研究。研究中考虑了激光的能量分布。实验结果表明,该模拟模型能较好地预测枝晶生长方向。此外,除了沿[100]方向生长的树枝晶区域外,对杂散晶分布的预测效果良好。
A vectorization analysis technique for crystal growth and microstructure development in single-crystal weld was developed in our previous work. Based on the vectorization method, crystal growth and stray grain distribution in laser surface remelting of single crystal superalloy CMSX-4 were investigated in combination of simulations with experimental observations. The energy distribution of laser was taken into consideration in this research. The experimental results demonstrate that the simulation model applies well in the prediction of dendrite growth direction. Moreover, the prediction of stray grain distribution works well except for the region of dendrites growing along the [100] direction.
