采用光学显微镜、扫描电子显微镜、X射线能谱仪和电子背散射衍射仪 ,研究了铁素体不锈钢—钢 (0Cr13Al/16MnR ,0Cr13Al/2 0g)、奥氏体不锈钢—钢 (1Cr18Ni9Ti/Q2 35A ,0Cr18Ni10Ti/16MnR)和双相不锈钢—钢 (0 0Cr2 2Ni5Mo3N/Q345C)三类爆炸复合钢板结合区的显微组织特征。发现结合界面呈准正弦波状结合 ,热处理后结合区基板脱碳、复板渗碳 ,而且在复合界面复板侧有一个超细晶粒带 ,热处理达一定时间后 ,基板脱碳界面与板面平行
The microstructures of ferritic stainless steels (0Cr13Al / 16MnR, 0Cr13Al / 20g) and austenitic stainless steels (1Cr18Ni9Ti / Q235A) were investigated by optical microscope, scanning electron microscopy, X-ray energy dispersive spectroscopy and electron backscatter diffractometer. , 0Cr18Ni10Ti / 16MnR) and the duplex stainless steel-steel (0 0Cr2 2Ni5Mo3N / Q345C) three explosive composite plate bonding zone microstructure characteristics. The bonding interface was found to be quasi-sinusoidal. After the heat treatment, the substrate of the bonding region was decarbonized and the composite plate was carburized. At the composite interface, the composite plate had an ultrafine grain belt. After the heat treatment for a certain period of time, parallel
