  • AbstractWe investigate the influence of \(Al_3(Sc,Zr)\) precipitates on the cold deformability and friction stir welding behavior of a novel AlMg4Sc0.4Zr0.12 alloy. To analyze the influence of the precipitate state on the flow stress, samples were pre-aged at various temperatures for up to 120 min prior to plane strain compression. It was found that the flow stress increased considerably with increasing pre-ageing temperature and duration. The formation of \(Al_3(Sc,Zr)\) precipitates during friction stir welding was investigated on welds with high and low heat input by measuring the respective hardening response with and without post-weld heat treatment.
