Aimed at magnesium alloys under uniaxial tension and compression conditions, the Schmid factor distribution of different slip systems(the basal slip, the prismatic slip, pyramidal <a> and <c+a> slips)in the whole orientation space is calculated.Results show that in the deformation process of magnesium alloys, the schmid factors for the basal slip, the prismatic slip and pyramidal <c+a> slip all have a maximum value of 0.5 in the whole orientation space;while the Schmid factor for pyramidal <a> slip is generally low, reaching the maximum value of only 0.383 when θ is approximately 80° and Ψ is 70°.The calculation provides a basis for analyzing the deformation mechanisms of magnesium alloys.
