摘要

为了减少焊接过程中Fe-Al金属间化合物（IMCs）的形成。通过对303不锈钢（SS）和6063铝（Al）合金的焊接结构设计和受力的合理控制，改变了两者的热分布和产热效率。铝合金的塑性流动使焊接热分布更加合理，局部区域可获得均匀连续的IMCs层或无IMCs层的Al/SS接头。对接头的组织和力学性能进行了详细分析。焊缝熔核的晶粒尺寸得到充分细化。节理的压剪力可达2.41 kN，节理断裂方式为脆性断裂。

Force-joule heat synergy for heat control in inhibiting intermetallic compounds during joining of 303 stainless steel and 6063 aluminium alloy

In order to reduce the formation of Fe-Al intermetallic compounds (IMCs) in the welding process. The heat distribution and heat production efficiency of 303 stainless steel (SS) and 6063 aluminium (Al) alloy are changed through the design of welding structure and the rational control of the force in the pressure resistance welding (PRW). The plastic flow of Al alloy makes the welding heat distribution more reasonable, and Al/SS joints with uniform continuous IMCs layer or no IMCs layer can be obtained in local areas. The microstructure and mechanical properties of the joint were analyzed in detail. The grain size of the weld nugget is fully refined. The compressive-shear force of the joint can reach 2.41 kN, and the fracture mode of the joint is brittle fracture.
