摘　　要：Aluminum 5052(Al 5052)-stainless steel 316(SS 316)plates were explosively cladded with Al 1100,pure copper and SS 304 interlayers.The operational parameters viz.,standoff distance,explosive mass ratio(mass ratio of the explosive to the flyer plate)and inclination angle were varied and the results were presented.The advent of interlayer relocates the lower boundary of the welding window,and enhances the welding regime by 40%.A triaxial welding window,considering the influence of the third operational parameter,was developed as well.Use of interlayer transforms the continuous molten layer formed in the traditional Al 5052-SS 316 explosive clad interfaces into a smooth interface devoid or with a slender presence of intermetallic compounds.The microhardness,ram tensile and shear strengths of the interlayered clads are higher than those of the traditional explosive clads,and the maximum values are witnessed for stainless steel interlaced Al 5052-SS 316 explosive clads.以1100铝、纯铜和304不锈钢为夹层,用爆炸复合法制备5052铝-316不锈钢(Al 5052-SS 316)复合板。采用不同工艺参数,包括相隔距离、炸药质量比(炸药质量与飞片质量比)和倾斜角得到实验结果。夹层的使用使焊接窗口的下边界发生位移,焊接区域增大40%。在此基础上,设计考虑第三个操作参数影响的三轴焊接窗口。使用夹层后,传统Al 5052-SS 316炸药复合界面形成的连续熔融层转变为光滑的界面,其中没有或存在少量的金属间化合物。含夹层复合层的显微硬度、抗拉强度和剪切强度均高于传统爆炸复合层,且使用不锈钢夹层的Al5052-SS 316爆炸复合层具有最高的显微硬度、抗拉强度和剪切强度。
