Numerical Simulation of Cellular/ Dendrite Arm Spacing Selection During Unidirectional Solidification of Ti-Al Alloy

The results show that, after laser surface processing, a melt layer with cellular dendrite structure is formed, which could transform into very fine grained structure during the annealing treatment.

结果表明，激光处理后试样表面熔凝区的组织主要为胞状枝晶组织，经后续热处理可转变为细小的等轴晶粒组织，并形成了良好的超塑连接条件。
