Microstructure and mechanical properties of Mg-Al-Sn-Ca alloy extruded by asymmetric severe shear extrusion with different asymmetric coefficients
Source abstract
Abstract
Magnesium alloys with grain refinement and texture weakening are long-term targets in the field of light alloys . A new asymmetric severe shear extrusion (ASSE) process is developed in this paper, which is specially designed to refine the grain and weaken the texture of deformed magnesium alloys. The effect of asymmetry coefficient (AC) on microstructure and properties of extruded products was studied. The results show that ASSE can effectively change metal flow. AC-1.5 shows the best mechanical properties, grain refinement (∼8.6 µm) and texture weakening. The yield strength is about 175.9 MPa and elongation is about 19 %. This study provides a theoretical basis for the further development of partial symmetric extrusion.
