“…Furthermore, minor presence of prismatic texture was observed for samples processed with low total input energies (higher tool linear velocities). It has been reported that the prismatic slip system experiences relative increase in activity during the deformation in following conditions: i) presence of solute alloying elements leading to ease of prismatic slip activation due to reduction in Peierls stress [2,76,77] ; ii) strain levels greater than 0.008 during the deformation process [78,79] ; and iii) higher temperatures during the deformation process easing the thermal activation of the prismatic slip system [80,81] . In the present case, the AZ31B Mg alloy has aluminum and zinc in the solid solution of α-Mg.…”

“…After CWLA processing, large number of tension twins were generated in the microstructure. It was calculated that Schmidt factor (SF) values of the pre-twinned samples with {1-100} < 11-20 > pyramidal slip system for most grains possessing twin lamellas focused on 0.4-0.5, which was very favorable for the tensile deformation along RD [28]. Thus, the pyramidal slip with high CRSS was operated in the early stage of the tension deformation.…”

In this study, a method of corrugated width limit alignment processes (CWLA) was applied to pre-twin in hot-rolled Mg alloy sheets. The microstructure evolution and mechanical properties of the CWLA sheets were studied. The results demonstrated that the grain orientation was transformed from strong basal texture to RD-rotated texture after CWLA treatment and up to 22.2% of {10-12} tensile twin boundaries were produced in the microstructure. The 60 ± 5° < 10-10 > twin variant pairs were dominant in the twinned microstructure. Two kinds of dynamic recrystallization (DRX) mechanism, i.e., continuous DRX (CDRX) at low-temperature CWLA and the discontinuous DRX (DDRX) at high-temperature condition were observed. After post-annealing, the twin-induced static recrystallization (SRX) and abnormal grain growth were observed in the CWLA samples, and most twin boundaries were retained. After CAWL for 60 min at 300 °C and post annealing, an improvement on plasticity and strength were achieved with 55% increment for uniform elongation (UE) and 10% increment for ultimate tensile strength (UTS).

“…It is a common and effective measure to refine grains by the plastic deformation of metal materials [ 5 ]. Dynamic recrystallization (DRX) often occurs in the process of plastic deformation, which can achieve the effect of grain refinement, leading to the improvement of mechanical properties [ 3 , 6 , 7 ].…”

Recrystallization Behavior of a Mg-5Zn Alloy Influenced by Minor SiCp during Hot Compression

The influence of minor SiCp on the dynamic recrystallization (DRX) and dynamic precipitation behaviors of the Mg-5Zn matrix were investigated through the hot compression test. The results showed that the addition of SiCp improved the DRXed ratio of Mg-5Zn matrix, but the recrystallized grains in 1 vol.% 5 μm SiCp/Mg-5Zn material were mainly formed by the “bulging” nucleation of the grain boundary at a low compressive strain (~0.05, ~0.1 and ~0.35), and PDZ (particle deformation zone) around SiCp had little effect on the recrystallization nucleation. However, the fine recrystallized grains appeared around the particles when the compressive strain reached ~0.7, which was attributed to the promotion effect of PDZ on recrystallization nucleation. This shows that PDZ around particles can promote DRX nucleation under large strain. Meanwhile, compared to the Mg-5Zn alloy, the volume fraction and size of the secondary phase in the SiCp/Mg-5Zn material increased due to the influence of SiCp on the recrystallization behavior of Mg-5Zn matrix.
