Influence of specimen width on the deformation and fracture behaviour of AA5182 sheets

•We examined the dependency of the specimen width on the tensile ductility of AA5182 sheets.•The tensile ductility showed a maximum at a specimen width of 12.5mm.•During strain hardening, the alloy displayed typical serrations due to the Portevin-Le Chatelier effect.•The results were satisfactory ex...
