Research Progress on Shear-Induced Texture Weakening and Property Improvement of Magnesium Alloy Thin Sheet
Due to the restriction of strong basal texture,the formability of the thin magnesium alloy sheets at room temperature is insufficient,and their industrial application is greatly limited.Based on the mechanism of texture weakening of Mg alloy sheets,this paper highlighted the feasibility and unclear mechanism problems of shear-induced twinning activation to realize texture weakening of magnesium alloy sheets.Combined with the process development for activating twinning to weaken the texture of magnesium alloy sheets,the features and limations of shear contained technology in Mg alloy sheets were discussed.Given the undelying mechanism of slip and twinning actviaiton under complex stress and lacing of technology for shear-induced texture weakening of Mg alloys,an effective Schmid factor and an equal channel angular bending technology were proposed,and the application of the new calculation theory and shear processing technology in Mg alloy sheets was presented.
