Abstract

The goal of this research is to study the influence of the ratio of an explosive composed of 80% ANFO and 20% matrix on the quality of dissimilar explosive welds of Cu-DHP copper to aluminium alloy 5083-H11, in flat configuration. It is analysed the influence of four explosive ratios (1.4, 1.8, 2.3 and 2.6) on the microstructure and mechanical properties of welds. It was observed that the increase in the explosive ratio gives rise to an increase of the collision point velocity (Vc) and the impact velocity (Vp) and consequently reduces the thickness of the flying plate after welding as well as produces wavy interfaces of greater amplitude. Microstructural analysis showed the formation of hard and brittle intermetallic compounds in the interface region, more obvious in welds made with higher ratio of explosive.

炸药配比对铜铝爆炸焊接质量的影响
本研究的目的是研究一种由80%铵油和20%基体组成的炸药的比例对Cu-DHP铜铝合金5083-H11在平面构型下不同爆炸焊缝质量的影响。分析了4种爆炸比(1.4、1.8、2.3和2.6)对焊缝组织和力学性能的影响。结果表明,爆炸比的增大引起碰撞点速度(Vc)和冲击速度(Vp)的增大,从而减小焊后飞板的厚度,并产生更大振幅的波状界面。显微组织分析表明,界面区形成了硬脆的金属间化合物,在炸药掺量较高的焊缝中更为明显。
