采用不同热轧压下率,对06Cr13/Q345R爆炸复合板进行了轧制实验。采用超景深显微镜和扫描电镜(SEM)分别对不同热轧压下率的06Cr13/Q345R爆炸+轧制复合板微观组织和拉伸断口进行了研究。结果表明:轧制后的06Cr13/Q345R爆炸复合板消除了爆炸产生的熔化区、空洞等缺陷;随着轧制压下率的增大,复合板的微观组织细化程度增加;热轧后,拉伸断口都是延性断裂,有非常明显的大量韧窝。 Using different hot rolling reduction rate, 06Cr13 / Q345R explosive composite plate rolling experiment. The microstructure and tensile fracture of 06Cr13 / Q345R detonation + rolled clad plate with different hot rolling reduction rates were studied by using the depth of field microscope and scanning electron microscope (SEM). The results show that the 06Cr13 / Q345R explosive composite plate after rolling eliminates the defects such as the melting zone and the cavity caused by the explosion. The microstructure refinement of the composite plate increases with the increase of rolling reduction rate. After the hot rolling, Tensile fracture is ductile fracture, a very significant number of dimples.
