Research progress on texture control of wrought magnesium alloys
Wrought magnesium alloys are prone to strong basal texture,resulting in poor room temperature plasticity and severe anisotropy,greatly limiting their applications.Research has found that weakening the basal texture can effectively improve the plasticity of magnesium alloys,and rare earth elements such as Gd,Y,Ce and Nd are effective texture optimization elements for magnesium alloys.The addition of these rare earth elements can cause changes in the intrinsic parameters of the material,thereby changing the mode of dislocation movement and improving the non-basal slip activity,thereby improving the material's formability.In addition,different processing methods or adjusting deformation process parameters,regulating the recrystallization process,and using special deformation processes can all be used to regulate the texture of magnesium alloys.Therefore,this article summarizes the research achievements in texture control of magnesium alloys in recent years,and discusses in detail the effects of the above methods on the texture types and strength of magnesium alloys,providing a reference basis for the design and development of high-strength plastic magnesium alloys.
