A new physical simulation tool to predict the interface of dissimilar aluminum to steel welds performed by Friction Melt Bonding [PDF]
Optimization of the intermetallic layer thickness and the suppression of interfacial defects are key elements to improve the load bearing capacity of dissimilar joints. However, till date we do not have a systematic tool to investigate the dissimilar joints and the intermetallic properties produced by a welding condition. Friction Melt Bonding (FMB) is
