The rules reflected by the curve are fitted to primary and secondary dendrite.

这一曲线关系所反映的规律可以用于一次枝晶和二次枝晶。

Gscoh gs fsR, gscoh as the solid fraction when the formation of the continuous dendrite framework, fsR as the maximum solid fraction after recalescence,βs as the solidification shrinkage of the primary phase,μas the dynamic viscosity of the liquid, a as the length of L/S coexistence zone,λ2 as the secondary dendrite arm spacing, and tf as the total solidification time. High temperature recovery and recrystallization taking place in these fragments during further cooling results in the further grain size decrease.

本文通过对过冷DD3高温合金再辉过程中累积应力的计算，得到作用于初生枝晶的累积应力σs，可表示为：式中，gl是液相体积分数，gs是固相体积分数，gscoh是连续枝晶网络形成点对应的固相分数，fsR是再辉结束后固相分数，βs是快速凝固中液固收缩率，μ为液态合金的动力学粘度，a是再辉中液固共存区长度，λ2是枝晶二次间距，tf是总凝固时间，即再辉时间。

The mature of pseudo-recalescence is the remelting of dendrites. This leads to apparent refinement of dendrite microstructures. Therefore the experiment support the viewpoint of dendrite remelting for microstructure refinement during supercooling solidification.②Under the condition of supercooling solidification, secondary recalescence cannot show up for single phase solid solution.

伪再辉现象的本质是枝晶熔断所致，由此引起伪再辉试样微观组织被明显细化，从而支持了深过冷凝固过程中组织细化的枝晶熔断说观点；②单相固熔体合金，在深过冷凝固条件下，不可能出现二次再辉。
