摘要
Fe -C -Mn三元合金在先共析铁素体形核和长大过程中 ,在铁素体和奥氏体晶界处会发生Mn的晶界偏析和溶质的拖曳效应。本文提出一种预测连续冷却过程中奥氏体向铁素体开始转变温度的计算方法 ,用该方法预测的结果与实测值相当吻合。
Synopsis For ternary alloy of Fe-C-Mn, the segregation of manganese and the solute drag effect will take place at the interface of ferrite-austenite during the process of proeutectoid ferrite nucleation and growth. A new approach to predict the beginning temperature of austenite-to-ferrite transformation during continuous cooling process is proposed and the predicted results are in good accordance with the measured values.
