The result shows that the RE make CCT curve move towards right and hardness of steel increases at same rate of cooling.
结果表明：稀土使钢的过冷奥氏体转变曲线右移，在同样冷却速度下，加稀土钢的硬度增加。
Its CCT curve was determined by test. The influence of quenching and tempering temperature on the mechanical properties was also studied.
试验测定了该钢的CCT曲线，探讨了淬火和回火加热温度对该钢力学性能的影响。
The deformation moves CCT curve to left and up direction. the cooling transformation initiating temperature of austenite increases more with the increase of cooling rate.
变形使CCT曲线向左上方移动，提高了奥氏体冷却转变开始温度，随冷速加大提高得越多。
