Abstract Explosive welds of stainless steel and aluminium could only be achieved with the steel positioned as the baseplate. Using stainless steel as the flyer plate, the tensile stresses arrive at the interface before the complete solidification of the localised melting and no bonding is achieved. The poor weldability in this configuration is mainly related to the very low thermal conductivity of the flyer compared to the baseplate. The position of the materials significantly influences the weldability, and the ideal material for the flyer should have a higher melting temperature, specific heat and thermal conductivity, and a lower density compared to the baseplate. Some intermetallic formation is inevitable in dissimilar welds of combinations that can easily form intermetallic phases. The time-velocity diagram proved to be a reliable tool to analyse the weldability, especially when used in conjunction with the weldability window.

铝与不锈钢的爆炸焊接

摘要 不锈钢和铝的爆炸焊接只能以钢为底板来实现。使用不锈钢作为飞板，拉伸应力在局部熔化完全凝固之前到达界面，并且没有实现结合。这种配置中较差的可焊性主要与传单与底板相比非常低的热导率有关。材料的位置对可焊性有很大影响，与基板相比，传单的理想材料应具有更高的熔化温度、比热和热导率以及更低的密度。在容易形成金属间相的组合的异种焊缝中，不可避免地会形成一些金属间化合物。
