Abstract Scope |
Kink banding in magnesium (Mg)-based long-period stacking ordered (LPSO) single phase alloy is studied by crystal plasticity finite element analysis, where basal and prismatic slip systems are taken into account. The numerical analysis reproduces formation processes of kink bands in single- and poly-crystals under various loading history including tensile, compressive or shear loading. While dominant kink-mode slip localization is developed by accumulation of basal slip, prismatic slip also produces slight kink bands under the conditions where basal slip system is hardly activated. Based on the numerical results, development mechanism of kink bands in LPSO is discussed in terms of lattice rotation and non-uniform deformation. |
