Texture evolution in Mg-Al and Mg-RE alloy during hot extrusion

摘要：

　　The application of Mg alloys is greatly restricted because of their poor plasticity, which is closely related with the texture formed during hot forming. In this paper, the texture evolutions in Mg-Al and Mg-RE alloy during extrusion have been investigated. The results suggested that the texture of Mg alloy extrusion bar and tubes could be weakened by Ce addition with small content, but it does not work when Al is also exists. Thus, the Mg-RE alloys exhibit much higher tensile elongation and good yield symmetry. The mechanism of texture weakening by RE addition is due to the solute effect, which could surpass the twinning and activated non-basal slip.
