| 摘 要： | 为了获得焊接后性能稳定的多层金属板,该文通过调节金属板层间间距和添加撞击板,对七层和十一层铝板进行了爆炸焊接研究。将层合材料进行切割分析,由结合界面的显微金相照片可知块体焊接质量良好;显微硬度分析表明,材料结合界面附近区域硬度有所增加且各界面处硬度波动不大,证明各层的相互撞击速度基本一致。该文研究结果为控制层间撞击速度,使其达到基本一致,且接近焊接下限提供了解决方法。

| Abstract: | In order to obtain the multilayer metal plates with stable property after welding,the spaces between two metal plates are regulated,an impact plate is added,and the explosive welding experiment on the seven-layer and eleven-layer aluminum plates are done.The multilayer plates are cut and analyzed.The metallographs of the bonding interfaces show that the bonding wave is small and good.The micro-hardness analysis indicates that the hardness near the interface is higher and each welding interface is approximat... |
