| 摘 要： | 不同参数下对1．6mm厚7075铝合金板进行了搅拌摩擦焊接，在分析了焊缝表面组织的基础上，采用浸泡试验对焊缝表面的腐蚀行为进行研究，讨论了硬度分布与腐蚀发生的关系。结果表明，焊后轴肩作用区晶粒细化明显。随转速的增加，焊缝上表面热机械影响区范围加宽、轴肩作用区硬度增大。焊缝上表面腐蚀最严重的区域为轴肩作用区，在EXCO溶...

| Abstract: | Friction stir welding(FSW) for 1.6 mm thickness 7075 aluminum alloy sheets with different processing parameters was carried out.Based on the analysis of the microstructures of the joint surface,the corrosion behavior was investigated by immersion test.The correlation between the micro-hardness distribution and the corrosion was discussed.The results showed that the grains in the shoulder active zone(SAZ) were obviously refined with the increase of the rotational speed.The spans of the thermomechanically-aff... |
