用透射电镜研究了0.11C～1.5Mn低合金钢,在临界退火过程中奥氏体的形核机制。认为,奥氏体主要在珠光体/铁素体、珠光体/珠光体和渗碳体/铁素体界面上形核;长时间退火后,奥氏体也可在铁素体
The nucleation mechanism of austenite during the critical annealing process was studied by transmission electron microscopy (TEM) for 0.11C ~ 1.5Mn low alloy steel. It is considered that austenite nucleates mainly at the interface of pearlite / ferrite, pearlite / pearlite and cementite / ferrite; after long time annealing, austenite can also be ferrite
