Ductility Enhancement in Mg Alloys by Anisotropy Engineering Conference Paper

abstract

• The Minerals, Metals & Materials Society 2017. A mean-field theory suggests that certain forms of plastic anisotropy hinder ductile damage accumulation. Here, a proof-of-concept is presented in the case of MgAlZn alloys. Textures produced by severe plastic deformation are compared with the as-received rolling texture in terms of their anisotropy-ductility correlations at ambient temperature. The 3D plastic anisotropy is characterized in each material using compression specimens. The ductility is characterized using tensile bars. A micromechanical model is introduced to rationalize the trends in terms of the anisotropy effect on ductility (AED) index. Here, this index is tuned via texture manipulations at fixed chemical composition and grain size. The main finding suggests that plastic anisotropy can be engineered to aid ductility.
