Influence of temperature and plastic deformation on AA2024 T3 friction stir welded joint microstructure

This paper deals with analysis and comparison of the equivalent plastic strain temperature fields in aluminium alloy 2024 T3 (AA2024 T3) joint, macro/microstructure appearance hardness profile. In alloys hardened by heat treatment, grain size particle precipitate are functions strain, rate temperature. By analysing it is possible, to some extent, capture effect welding parameters thermo-mechanical conditions on structure, therefore strength welded joint. A coupled model applied study material behaviour during linear stage friction stir welding. The 3-D finite element has been created ABAQUS/EXPLICIT software using Johnson-Cook law. values quantities obtained from numerical shown as distributions across these related microstructure joint zones distribution, this relation discussed.
