Abstract: Compression experiments were carried out along the extrusion direction for the extruded WE43 magnesium alloy material. By means of SEM/EBSD characterization, comparative analyses of the original specimens and the deformed specimens with strain variables of 0.15 and 0.25 after warm compression at 150 ℃ were carried out to study the microstructure evolution law and microplastic deformation mechanism of WE43 magnesium alloy under different strain variables. The results show that with the increase of strain, the grains are continuously refined, and the total volume fraction of twin crystals increases first and then decreases. The deformation is driven by the activation of a large number of identical and relative twinned variants, which drives the transition of the initial weave, 〈1010〉//ED, which favors nonbasal slip, toward the orientation 〈0001〉//ED, which favors basal slip. Comparing dynamic recrystallization induced by tensile and secondary twins, it indicates that tensile twins have a greater potential than secondary twins in refining the tissue structure. Dynamic recrystallization modes include continuous dynamic recrystallization and second-phase particle-induced dynamic recrystallization in addition to twin-induced dynamic recrystallization.
