用透射电镜研究了爆炸焊接复合板００Ｃｒ１８Ｎｉ５Ｍｏ３Ｓｉ２／１６Ｍｎ的结合界面。结果表明：爆炸焊接复合板的宏观界面为锯齿形；齿间的基板和覆板受强大爆炸冲击力的作用形成几微米宽的过渡区，该区内位错密度增大，并有细小的覆板碎屑存在。齿部边缘的晶粒破碎，齿尖部位有熔化现象，这主要是基于３个方面的原因：一是齿尖处有毛细管状沟槽组织存在；二是齿尖周围有析出物出现；三是齿尖与覆板的铬含量有一定差异 The bonding interface of the explosive welding clad plate 00Cr18Ni5Mo3Si2 / 16Mn was studied by transmission electron microscope. The results show that the macroscopic interface of the explosive welding composite plate is zigzag; the interdend plate and the cladding plate are affected by the powerful blasting force to form the transition zone of several micrometers wide. The dislocation density increases in this zone with a small coating Plate debris exists. Tooth edge of the grain crushing, tooth tip melting phenomenon, which is mainly based on three reasons: First, the presence of capillary groove-like tissue at the tooth tip; the second is the presence of precipitates around the tooth tip; the third is There is a certain difference between the chrome content of the tooth tip and the cover plate
