摘要

研究了高强度7075铝合金在3 mm厚板搅拌摩擦焊接过程中的组织特征和性能的形成。在焊接过程中，通过实施补充液体冷却技术，形成高质量永久接头的可能性被展示。经水冷却焊接后试样的抗拉强度是母材强度的0.9倍。在处理后时效的情况下，发现焊缝的强度超过母材的强度。

Formation of al-zn-cu-mg alloy joint structure under friction stir welding with additional liquid cooling and subsequent artificial aging

The structure characteristics and the formation of properties of high-strength aluminum alloy 7075 are studied during friction stir welding of 3 mm thick plates. A possibility of forming a high-quality, permanent joint by the implementation of supplementary liquid cooling techniques during the welding process is shown. The tensile strength of the samples welded with water cooling is observed to exceed the base metal strength by 0.9 times. In the case of post-treatment aging, the strength of the welds is found to exceed that of the base metal.
