Abstract
The dissimilar connection between 6082 aluminum alloy and 304 stainless steel was realized by continuous drive friction welding. Microstructures of the joint were studied by optical microscopy (OM), scanning electron microscopy (SEM) and X-ray diffractometry (XRD). In the process of continuous drive welding, the intermetallic compounds (IMCs) Fe2Al5 phase was observed at the interface, the formation mechanism of IMC was discussed, and the corresponding analysis model was established. When the upset pressure in the range of 6–10 MPa, the element diffusion distance increases with the increase of upset pressure. The tensile strength of the joint increased firstly and then decreased with the increase of upset pressure. The joint’s maximum tensile strength can reach 234 MPa, and tensile fracture of the joint exhibited brittle-tough mixed fracture characteristics.
