摘　　要：测定了09CuPCrNi耐候钢的连续冷却转变动力学图(CCT曲线),并对不同冷速下的组织进行了观察。与传统09CuPCrNi耐候钢的CCT曲线相比,加入0.33%(质量分数,下同)的Mo后,贝氏体转变区与铁素体转变区部分分离;加入0.41%的Mo后,贝氏体转变区与铁素体转变区完全分离,同时珠光体转变区与铁素体转变区也完全分离。CCT diagrams and microstructure of 09CuPCrNi steels were investigated using dilatometric method and optical microscopy respectively. Compared with that of the CCT diagram of the conventional 09CuPCrNi steel, the transformation range of bainite is partly separated from that of ferrite when the adding amount of Mo is 0. 33% wt, and they are completely separated when the amount of Mo is 0.41% wt, also the transformation ranges of pearlite and bainite are separated completely.
