Q460C钢的连续冷却转变曲线OA
Continuous Cooling Transformation Curve of Q460C Steel
研究了Q460C钢连续冷却过程中奥氏体转变过程以及转变产物的组织变化,为制定生产工艺提供参考依据.由Q460C钢的连续冷却转变曲线(CCT图)和不同冷却速率的显微组织可知,当冷却速率较低时,形成粗大的块状铁素体和珠光体;当冷却速率大于3℃/s时出现贝氏体,形态似针状铁素体,其形成温度在450～600℃;当冷却速率大于15℃/s时,发生马氏体转变,马氏体的转变点约为350℃.
Transformation of austenite and morphology of its product in the continuous cooling process of Q460C steel were investigated in order to provide references for industrial production.From the continuous cooling transformation curve (CCT curve) and the morphology at different cooling rate which indicated that massive morphology of ferrite and pearlite could be easily formed when the cooling rate was relatively low,the bainite,whose formation temperature was ab…查看全部>>
