| 摘 要： | 分析了不同偏束距离对铝合金/钢异种金属EBW接头的组织形态、化合物层厚度、裂纹缺陷以及接头性能的影响.结果表明,随着偏束距离的增加,焊缝中的Fe-A l化合物颗粒逐渐消失,晶界上的共晶体减少,化合物层形态由复杂变简单,厚度减小.偏束距离较小时,在化合物层附近的焊缝中存在裂纹缺陷;偏束距离较大时,在化合物层上存在裂纹.偏...

| Abstract: | Effect of different beam offset on microstructure configuration,thickness of intermetallic compound layers,crack defects and mechanical properties of aluminum alloy/steel electron beam welded joints was analyzed.The results showed that with the increment of beam offset,the Fe-Al intermetallic compound grains in the weld vanished,gradually the eutectic substance on the crystal border decreased,and the configuration of the intermetallic compound layer became less complicated and the thickness of it became sma... |
