| 摘 要： | 采用热膨胀法和金相法，在Formastor-F试验机上测定了含Ti系微合金热轧搪瓷钢RT360的Ac1和Ac3以及Ms，并测定了该钢在不同冷却速度下连续冷却时的膨胀曲线，获得了该钢的连续冷却转变曲线(CCT曲线)及其相应组织，测定结果为大生产热处理工艺的制定提供了理论基础.当轧后冷却速率＜0.5 ℃/s，可获得理想的多边形铁素体＋少量珠光体组织.淬硬性倾向较小，基本不会出现冷裂纹.

| Abstract: | By dilatometric change referencing microscopic test and hardness measurement， the critical point at Ac1， Ac3 long with Ms of Ti-bearing microalloyed hot-rolled enamel steel was determined in Formastor-F thermalmechanical simulate. The different expanding curves of Continuous Cooling Transformation CCT diagram was measured. The CCT diagram provided the theoretical basis for the design of rolling and cooling process. When the cooling rate was less than 0.5 ℃/s， the ideal polygon ferrite and a small amount of pearlite is able to be generated. Thanks to the small hardening tendency， the cold crack would not appear in the matrix. |
