Presentation Title Novel Texture Controlling of Mg Alloys

Abstract Scope Conventionally extruded Mg alloy sheets possess poor mechanical properties due to the strong basal texture. This brings about a poor deformation capability of sheet thinning and a stronger anisotropy and consequently results in limited number of available plastic deformation modes. In this work, a novel extrusion approach to get high strength magnesium alloy plates will be introduced. A suitable constitutive model of differential speed extrusion is established to ameliorate the texture-dependent mechanical properties. The yield stress of AZ31 alloy sheet has been increased from 161.2 MPa to 179.9 MPa and the elongation has been improved from 15.4 % to 20.1 %. AZ61 alloy sheets’ ultimate tensile strength was increased from 387.9 MPa to 427.1 MPa and the yield stress was improved from 147.7 MPa to 195.9 MPa. Grain refinement and tilted weak basal texture obtained by differential speed extrusion process.
