A constitutive description of plastic deformation in the suggested scheme accounts for contributions from deformation slip and twinning. The calibrated model was employed to investigate the effects of texture and grain size on the yield stress and strain- - hardening behaviour of AM30 magnesium alloy at room temperatures under various loading conditions. The study reveals that grain refinement and initial texture significantly influence the mechanical behaviour of AM30. Results show that the key factor controlling the tension compression asymmetry is deformation twinning. Two techniques, which could be used to reduce this asymmetry, are grain refinement and weakening of the initial texture in extruded AM30.<br></div> AM30;Grain size;Texture;Crystal plasticity;Finite-element analysis;Mechanical Engineering not elsewhere classified 2019-09-26
