摘要
在GLEEBLE-3800热模拟试验机上对一种高强低碳贝氏体钢变形奥氏体连续冷却转变曲线（CCT曲线）进行测定，检测不同冷却速度下转变产物的显微组织。研究不同冷却速度下钢板的组织演变。结果表明，冷却速度控制在8—14℃／s，开冷温度在800℃左右，终冷温度在500—580℃，此时，组织均匀性最好。
A dynamic CCT curve of low carbon bainite steel was measured by GLEEBLE-3800 thermal simulator, and the microstructure at different cooling speeds was observed to study the microstructure evolution of the steel plate at different cooling speeds. The results showed that, the best structure uniformity was obtained under the cooling speed within 8 - 14 ℃/s, the start cooling temperature near 800 ℃ and the end cooling temperature within 500 - 580 ℃.
