## Description

- description: 'We employed the high-resolution digital image correlation study to
    investigate the plastic deformation of low-carbon lath martensite. The strain
    localization bands were mainly categorized into two types: boundary slips and
    intra-block deformation. Misorientation angle and inclination angle with respect
    to loading direction primarily determines the slip activation at boundaries. The
    competitive relationship between the activation of in-lath-plane and out-of-lath-plane
    slip systems follows the Schmid effect. The in-lath-plane slip systems were only
    activated in blocks with high in-lath Schmid factor (SF) value. The out-of-lath-plane
    slip systems were activated only when its SF is much higher than the maximum in-lath
    SF, offsetting the effect of the higher critical resolved shear stress (CRSS)
    for in-lath-plane slip systems. Moreover, the block morphology also affects the
    slip activation behaviour: in-lath-plane slip systems in columnar blocks were
    preferentially activated due to both crystallographic dynamics and strain accommodation.
    In contrast, out-of-plane slip systems were only observed in equiaxed blocks where
    the boundary effect is weakened. '
