分别采用等厚度装药及分段装药两种不同的装药方式制备了钛/钢复合板，研究了金属复合板在爆炸焊接过程中爆炸压力分布及覆层金属变形规律，并对所制备的Gr1/Gr70爆炸复合板结合界面的微观组织特征和力学性能进行了分析。结果表明，采用分段装药工艺所制备的大面积钛/钢复合板界面无分层、夹杂等缺陷，且各项力学性能均符合ASTM B898-2005标准，能够满足装备的使用要求。
In this study,titanium clad steel plates Gr1/Gr70 were joined explosively employing different dynamite loading modes,which were uniform thickness dynamite loading and segment dynamite loading,respectively. The pres-sure distribution and the deformation law of clad layer were studied. Then the interface microstructure characteristics and mechanical properties of the prepared clad plates were also analyzed. The results show that there are no delamina-tions,inclusions and other defects existed in the interface when segment dynamite loading was used to produce the large area titanium/steel clad plate. Moreover,the mechanical properties are content with the standard ASTM B898-2005 and meet the requirements of equipment service.
