Prediction and Experimental verification of Phase transformation Critical Temperature and Cooling velocity of low-alloying steel 低合金结构钢相变特征温度和冷速的计算机预报预测及实验验证
The content of pro-eutectoid ferrite decreases with increase of cooling velocity. The precipitation of pro-eutectoid ferrite is restrained completely, when the cooling velocity gets to 100 K/ min. In other words, the critical cooling velocity of ferrite is lower than 100 K/ min. 随着冷却速度的提高,先共析铁素体的含量逐渐减少,当冷却速度达到100K/min时,先共析铁素体的析出已完全被抑制,也就是说,铁素体的临界冷却速度低于100K/min。
