| Abstract Scope |
The automotive and transportation sectors are increasingly adopting lightweight multi-material combinations, such as aluminum, magnesium, and advanced/ultra-high strength steel (A/UHSS), to enhance vehicle performance and safety. This approach presents challenges, including liquid metal embrittlement (LME), corrosion, and deformation, necessitating non-traditional joining techniques. High Velocity (HiVe) is an innovative solid-phase processing method suitable for joining these dissimilar materials. This study uses a powder-actuated HiVe method, with and without steel rivets, to examine the dynamic deformation and interfacial bonding of various joints. HiVe processing was successfully applied to advanced high-strength steels (AHSS) such as dual phase (DP1180), retained austenite (RA1180), and press hardened steels (PHS1300), as well as aluminum and magnesium alloys (Al/Mg). Results show a nearly seven-fold increase in lap shear strength and elimination of LME in 3rd generation AHSS, significantly outperforming resistance spot welding and friction stir welding joints reported in existing literature. |
