Schematic representation of the interaction modes between ordered precipitates of Al₃Li and dislocations, in which the textured areas describe APB. (a) As-quenched condition [70]; (b) Under-aged condition [70]; (c) peak-aged condition [70]; (d) over-aged condition [70]; (e) The comparison between bowing and shearing mechanisms as a function of precipitates size (critical radius). L is the separation distance between the 1^st and 2^nd dislocation, besides, L₁ and L₂ are the particle spacing for the 1^st and 2^nd dislocation.
