“…The most common deformation modes are a basal slip, a prismatic slip, c + a pyramidal slip and tension twinning, where a basal slip and tension twinning are usually readily activated [8][9][10]. Over the past decades, a large amount of studies have been conducted to determine the influence of grain size [11][12][13], orientation [11,[14][15][16][17][18], two-phase [13,19] precipitates [20][21][22] and solutes [23][24][25][26] on the activity of these deformation modes. But less researches in duplex magnesium-lithium alloy have been carried on.…”

A crystal plasticity finite element model was proposed considering slip and twinning interactions. The grain morphology and crystallographic orientations were introduced into the model to describe the microstructure of duplex polycrystalline Mg–9Li–Al. The activation of the slip systems and the strain localisation with respect to initial grain orientations were investigated. In addition, the effects of phase distributions and volume fractions on the macroscopic responses and on strain hardening rates were analysed. The results show that the strain hardening is rate-dependent but the texture is less sensitive to strain rate. The distribution of a phase and its volume fraction play primary roles in governing the mechanical response. GRAPHICAL ABSTRACT
