TiAl alloys ; solute shock wave ; columnar to equiaxial transition

TiAl合金；成分冲击波；柱状晶/等轴晶转变

Solute diffusion controlled solidification model was employed to simulate the columnar to equiaxial transition of TiAl alloy casting. The simulation results show that solute shock wave occurs when the diffusion fields of columnar and equiaxial dendrites meet.

利用溶质扩散控制模型对TiAl合金柱状晶/等轴晶转变过程进行了数值模拟，结果表明，等轴晶在柱状晶前沿形核及生长过程中，当两个扩散场相遇时，观察到成分冲击波，它可能是导致柱状晶停止生长的一个主要原因。
