摘　　要：以H13钢晶粒尺寸为切入点,利用Jmatpro探讨晶粒度大小对TTT曲线的影响,得出了晶粒平均直径与珠光体转变时间的关系,提出了提高球化效果的方法。Taking the grain size of H13 steel as the starting point,the influence of grain size on TTT curve has been discussed by using Jmatpro.The relationship between the average grain diameter and pearlite transition time has been obtained,and the method to improve the spheroidization effect has been proposed.

关 键 词：H13钢 晶粒尺寸 TTT曲线 球化效果
