Abstract Scope |
The resistance spot welding (RSW) of advanced materials is of particular interest to the automotive industry for several reasons. These reasons include current industry needs for vehicle light-weighting while maintaining proper safety standards. Interest related to the development of lightweight vehicle structures is due to demands for both energy saving and improved fuel efficiency. Advanced high strength steels (AHSS) are pursued due to their high crashworthiness, strength, and improved design flexibility. Aluminum alloys are also integrated into these body-in-white designs for strength and lightweight. Despite the advantages associated with these materials, there are some challenges with RSW dissimilar (Al-AHSS) material combinations. The limited solubility of Fe in Al promotes the formation of brittle intermediate phases. The topic of interlayers is not new; however, limited information concerning the role of interlayer composition and deposition on the intermetallic formation and mechanical performance is available. The preliminary findings suggest that interlayer compositions with high chromium content effectively mitigate the intermetallic layer and improve mechanical performance for different conditions. |
