1) pre-eutectoid phase
先共析相
1.
The results show that the size of the pre-eutectoid phases decreases and the organizational distribution becomes more dispersive with the increase of cooling speed in the heat treatment course,and the shear deformation is caused in the later course of ECAP,then it becomes large during the anneal course.

补充资料：先共析铁素体
proeutectoidferrite：本意是低于共析成分的奥氏体，从高温慢冷下来之际，在发生共析相变（共析转变）之前析出的铁素体。
