The modified friction stir clinching (MFSC) of 5083 aluminum alloy to brass using pure Zn interlayer has been explored and elucidated for the first time. By that, the influence of the Zn interlayer thickness on the microstructure and the mechanical properties of the 5083/brass joint was investigated. The attained data have revealed that the intermetallic compound (IMC) layer thickness was mainly influenced by the Zn interlayer. The use of the Zn interlayer restrained the creation of brittle Al–Cu IMCs such as Al₄Cu₉ during the MFSC process and, in return, softer phases such as Cu₄Zn, CuZn_5, and CuZn were formed. It was also found that with increasing the thickness of the Zn interlayer from 50 to 100 µm, the thickness of the brazed zone increased and the tensile/shear strength of the spot welds significantly improved from 5250 to 8490 N (approximately 60% increment over the welded sample with 50-µm-thick Zn) which can be ascribed to supreme bonding and homogeneous brazing zone at the interface.

首次探索并阐明了使用纯Zn中间层将5083铝合金与黄铜进行改进的摩擦搅拌铆接（MFSC）。由此，研究了Zn中间层厚度对5083 /黄铜接头的组织和力学性能的影响。所得数据表明，金属间化合物（IMC）层的厚度主要受Zn中间层的影响。Zn夹层的使用可抑制在MFSC过程中脆性Al-Cu IMC（例如Al ₄ Cu _{9）的产生}，并抑制较软的相（例如Cu ₄ Zn，CuZn _{5）的产生。}形成了CuZn。还发现，随着Zn夹层的厚度从50 µm增加到100 µm，钎焊区的厚度增加，点焊的抗拉/剪切强度从5250 N显着提高到8490 N（相对于Zn层增加约60％）。厚度为50 µm的Zn焊接样品，可以归因于在界面处的最高粘结和均匀钎焊区。
