摘　　要：利用Formaster全自动相变膨胀仪对60钢的CCT曲线重新进行了测定,结果仅测到很窄的贝氏体形成范围,且是上贝氏体,没有发现韧性良好的下贝氏体析出,新测定的曲线与已报道的数据在贝氏体形成区域有较大差距。CCT curve of 60 steel was redetermined by using Formaster automatic dilatometer. The results show that there are apparent differences between the redetermined data and the reported one especially in bainite forming region. The bainite in redetermined samples had very narrow forming region. Moreover the precipitate is upper bainite and no lower bainite has found.
