The microstructure evolution and mechanical properties of AZ31 Mg sheets that was processed by rolling and subsequent annealing at lower temperature were investigated. The results indicated that few-pass rolling with large deformation is a better strategy to prepare AZ31 Mg sheets with higher deformation restored energy and less rolling defects. After annealing, the static recrystallisation occurred and the recrystallisation degree increases with the annealing temperature and time. Finally, the best comprehensive mechanical properties were obtained by 3-pass rolling with large deformation and annealing at 200 °C for 150 s and the corresponding YS, UTS and TEF of the AZ31 sheet were 225 MPa, 305 MPa and 32%, respectively. The improvement in the microstructure and mechanical properties can be attributed to an optimised static recrystallisation at a relatively low temperatures and in a short time.

“…Figure 9 shows the Schmid factor (SF) distributions of the {0001} 〈110〉 slip system of all sheets along the RD and TD. Usually, the SF closely related to the grain orientation, and the larger the SF, the more favorable the orientation is for basal slip [20]. With the increase of Ca content, SF obviously increases, and the difference of SFs along different directions becomes smaller.…”

Calcium (Ca), with abundant and cheap reserves, is a potential element to facilitate the further application of Mg-Al-Sn based alloys. Here, effects of Ca content on the microstructure and tensile properties of Mg-2.0Al-0.8Sn (wt.%) alloys were systematically studied. The experimental results illustrated that the strength, ductility and isotropy of the alloys improved simultaneously with the increase of Ca content. The better ductility and isotropy could be contributed to the weakened texture via particle stimulation nucleation mechanism. The higher strength benefited from the combination of finer grains, more precipitates and residual dislocation density. Eventually, the Mg-2.0Al-0.8Sn-0.5Ca (wt.%) alloy showed the best room-temperature balance of strength and ductility with a yield strength of ∼226.0 MPa, an ultimate tensile strength of ∼282.4 MPa and a fracture elongation of ∼20.2%, which has huge potential as an applicable low-cost high-performance magnesium alloy.

“…So a change in texture of the initial hot rolled material by CR process may subsequent affect the texture developed by cold rolling process. At the same time, it can also affect the mechanical properties of the material [15][16][17]. Hence, the current work is based on the hot rolling with change in RD and its effect on the tensile properties and plastic anisotropy of the rolled samples.…”

Rolling, at elevated temperature, with a change in the rolling direction (RD) have been conducted on 304 austenitic stainless steel. Two different sequences of change in RD, after each pass, have been followed viz., change in RD by 90°; designated as cross rolling (CR) and change in RD by 180°; designated as reverse rolling (RR). Effect of this change in RD on texture and tensile properties has been studied through Electron backscattered diffraction (EBSD) and uniaxial tensile test, respectively. In addition, tensile tests have been performed to study the anisotropy in tensile properties. The result shows a significant effect on the texture component formation. RR develops strong Cu and S components whereas CR forms strong Brass component. However, both the rolling sequence produces moderate Goss orientation. The observed tensile properties are correlated with the texture developed by both the processes.
