摘要
通过Gleeble2000和1500热模拟试验机,研究了0·75C共析钢珠光体和过冷奥氏体在压缩变形过程中的组织演变。试验结果表明,试样以10℃/s加热至700℃3min进行60%压缩变形,钢中珠光体片层发生断裂、破碎;试样加热至1150℃1min奥氏体化后以20℃/s冷却至700℃,压缩变形60%,在变形作用下,钢中部分过冷奥氏体转变成细片层珠光体。
The structure evolution of pearlite and overcooling austenite of 0. 75C eutectoid carbon steel during compression has been studied by Gleeble 2000 and 1500 thermal simulation machines. The test resulte showed that as sample heated with 10 ℃/s to 700℃ for 3 rain than carried out 60% reduction, the lamellar peadite in steel broke up and fractured; and as sample heated to 1 150 ℃ for 1 rain for austanization than cooled with 20 ℃/s to 700 ℃ and reduced by 60%, the partial overcooling austenite in steel transformed to fine lamellar pearlite under effect of defornmtion.
