Study on Texture and Anisotropy of Magnesium Alloy Based on Laser Vision Sensing

Abstract

Magnesium is the lightest metal material currently used, which has many advantages, such as high specific strength, specific stiffness, good electromagnetic shielding and damping performance, environmental friendliness, etc. It is an ideal lightweight metal shell material. 1. The texture and anisotropy of AZ31 magnesium alloy extruded sheet are studied based on laser vision sensing. The results show that the mechanical properties of Mg-Mn-Ce extruded pipes are obviously anisotropic, and the yield strength and tensile strength along the extrusion direction are obviously smaller than those in the transverse direction. There are some differences in metallographic structure along the wall thickness direction. The tensile yield strength in all directions is obviously greater than the compressive yield strength. Different rolling processes have significant effects on the mechanical properties of plates, which are mainly manifested in different yield stress and elongation. It is found that the texture evolution is dominated by dislocation slip during tensile deformation along, and the relationship between texture evolution and slip mechanism under uniaxial tension is established.
