interface morphology造句

• It was found that the interface morphology of ni , cr , al - tac eutectic in - situ composite evolved from plan to cell and then to dendrite with the increase of solidification rate , if the gradient retained constant . in the same time , the eutectic microstructure also evolved from rod to cell and then to dendrite
  本工作发现，在温度梯度基本保持不变的条件下，随着凝固速率的增大， ni ， cr ， al - tac共晶自生复合材料的凝固界面由平界面向胞状及枝状界面逐渐转化。
