| 摘 要： | 通过Gleeble 2000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 ℃ 3 min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℃1 min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。

| Abstract: | The structure evolution of pearlite and overcooling austenite of 0.75C eutectoid carbon steel during com- pression has been studied by Gleeble 2000 and 1500 thermal simulation machines.The test results showed that as sample heated with 10 ℃/s to700 ℃ for 3 min than carried out 60% reduction,the lamellar pearlite in steel broke up and frac- tured; and as sample heated to 1150 ℃ for 1 min for austenization than cooled with 20 ℃/8 to 700 ℃ and reduced by 60%,the partial overcooling austenite in steel transformed to fine lamellar pearlite under effect of deformation. |
