Microstructure evolution, texture development, and mechanical properties of hot-rolled 5052 aluminum alloy followed by annealing

Abstract Aluminum alloys, especially the 5000 series, have drawn attention of transportation industry due to their lightweight and consequently reduced fuel consumption. In this regard, one major problems alloy is its low strength ductility that can be solved using rolling post-annealing. Accordingly, present study concentrates on issue. Microstructural images showed process develops a lot tangled trapped dislocations in sample, which gradually lead formation dislocation bundles networks. Subsequent annealing produce more homogeneous structure with clear grain boundaries density inner region grains. However, refinement efficiency through retained even after annealing. Initial rolled Al5052 maximum intensity 2.87 6.33 possess lowest highest overall texture. Also, post-annealing decreases texture 4.87 at 150 200 °C, respectively. context, deformation components strengthen considerably shear bands, they slightly weaken during heat treatment. Although initial as-received material does not cause discontinuous recrystallization rolling, it may facilitate recovery before rolling. Post-annealing was found decrease improved effect by increase negative influence inhibition strengthening. The results both precipitation Mg atoms are influential for electrical resistivity.
