Charpy and SEM investigation of Al-Mg friction stir weldments
Апстракт
Influence of friction stir welding processing variables on Charpy impact fracture behaviour of Al-Mg 5083 alloy was studied. Rotational and traversal welding rates were linked to the dynamic crack initiation and ductile tearing. Fracture mechanism was examined by numerical and fractographic analysis. Results revealed that initiation and stable crack propagation were significantly influenced by applied heat input variables. It was attributed to the strain hardening of the investigated alloy. The final, unstable phase of the ductile tearing is strongly susceptible to the imperfections in the stirring zone of the welded joint.
