选用共析碳钢，研究了奥氏体区预变形对随后的奥氏体珠光体转变的影响。结果表明，由于奥氏体的预变形，奥氏体珠光体转变过程明显被加速，珠光体的形核部位由未变形时的晶界形核方式为主逐步发展到晶界、晶内同时形核。转变后的组织较未变形的明显细化。变形的影响在变形量为峰值应变量（应力达到峰值时对应的应变量）时表现最为突出。 The use of eutectoid carbon steel, austenite region pre-deformation on the subsequent austenite pearlite transformation. The results show that due to the pre-deformation of austenite, the transformation of the austenite pearlite is obviously accelerated. The nucleation site of pearlite mainly changes from the grain boundary nucleation without deformation to the grain boundary, nuclear. After the transformation of the organization was not significantly deformed. The effect of deformation is most pronounced when the amount of deformation is the amount of peak strain (the amount of strain corresponding to the peak stress).
