介绍了澳大利亚国防科技集团为提高军用车辆的生存能力和机动性而开发的一种新型爆炸焊接技术--通用替代爆炸焊接技术。新工艺在整体性、质量和稳定性方面上级现有的工业爆炸焊接工艺。它能够显著提高靶材的硬度上限，并确保飞片（软）和靶（硬）板之间的完美焊接结合，而不受靶板尺寸的限制。实验结果表明，使用新技术将爆炸焊接板的弹道速度极限（V-50）提高了20%，并显著降低了凸起深度（与动态塑性相关），而没有任何破裂或破碎问题。对新工艺制备的样品进行的夏比冲击试验表明，随着时间的推移，没有转变温度，具有很强的恢复效应。(C)2016爱思唯尔有限公司版权所有
This paper presents an innovative explosive welding technology, namely Universal Substitutive Explosive Welding technique, which was recently developed by Australian Defence Science and Technology Group to improve the survivability and mobility of military vehicles. The new technique is superior to the existing industrial explosive welding ones in terms of integrity, quality and stability. It is able to significantly upgrade the hardness upper limit of target material and ensure the perfect welding bond between the flyer (soft) and target (hard) panels without size limitation of target panel. Experimental results show that using the new technique raised the ballistic velocity limit (V-50) of the explosively welded panel by up to 20% and reduced the bulge depth (related to dynamic plasticity) significantly without any rupture or fragmentation issues. Charpy impact test on the sample fabricated by the new technique showed strong recovery effects with time with no transition temperature. (C) 2016 Elsevier Ltd. All rights reserved.
