Texture and Anisotropy of the Mechanical Properties of MA2-1, MA14, and Mg–5Li–3Al Alloys

Abstract

The anisotropy of the strength properties are compared with the averaged Schmid factors for the operating shear systems of textured pressed bars made of magnesium alloys MA2-1, MA14, and Mg–5Li–3Al in order to determine the ratios of the critical resolved shear stresses (CRSS) for the operating slip and twinning systems. In addition to the main deformation mode by basal slip in the MA2-1 and MA14 alloys, “tensile” {10\(\bar {1}\)2}〈10\(\bar {1}\)1〉 twinning and 〈\(\bar {c}\) + \(\bar {a}\)〉 slip are shown to be active. The ratio of the CRSS of these systems to the CRSS of the basal slip for the MA2-1 alloy is 1.7 and 2.2, respectively; for MA14, it is 1.5 and 1.8, respectively, which causes a lower anisotropy of the strength of the MA14 alloy and a more intense prismatic texture. For the alloy with lithium, the main deformation mechanism apart from basal slip is prismatic slip, for which the relative values of CRSS are 1.4 (which is lower as compared to other magnesium alloys). The results obtained make it possible to interpret the anisotropy of the properties in terms of Hill’s yield criterion, to calculate the corresponding anisotropy parameters, to plot yield locuses for the most common textures of semifinished products, and to show that the contribution of single-crystal anisotropy to the anisotropy of the strength properties significantly exceeds the contribution of the texture factor.
