Effect of pre-deformation anneal on the microstructure and texture evolution of Mg–3Al–1Zn–0.7Sr alloy during hot extrusion

Analysis of Abnormal Texture and Strengthening Mechanisms of Extruded Mg–Gd–Y–Nd–Zr Alloy

“…The extrusion temperature and ratio have a great influence on the microstructure, resulting in different grain sizes, orientations, and secondary phase characteristics, and ultimately affecting the mechanical properties. [ 12 ] Generally, a higher extrusion temperature results in coarser dynamic recrystallized (DRXed) grains and a lower volume fraction of the second phases, resulting in reduced tensile strength. [ 13 ] However, the extrusion ratio exhibits a complicated effect on the final microstructure and mechanical properties.…”
