The eutecticgrowth of cast iron during rapid solidification has been studied with laser remelting and deep etching.
采用激光快速熔凝和深腐蚀技术，对快速凝固过程中铸铁的共晶生长进行了研究。

The variation curves of the eutecticgrowth rates are approximately symmetric for the increase and decrease in the displacement velocity at the same acceleration.
当共晶试样增速和减速的加速度值相同时，实际共晶生长速度的变化过程呈对称的逆曲线。

Considering the appearance of solute trapping in non-equilibrium rapid solidification, its effect of solute trapping on the growth process was discussed basing on the existent eutectic models.
