Abstract
The effect of solution treatment on the spatial behavior of the Portevin-Le Chatelier effect in Al-Cu alloys is investigated under constant applied driving velocity. During the initial stage of plastic deformation, the PLC deformation band nucleates in the neighborhood of the middle of the transverse direction of specimen. And multiple bands will exist simultaneously in the specimen when deformation develops, whose width is narrower and incline at a larger angle than those in annealing treated material. At high applied velocity, the PLC deformation band propagates continuously first, and then nucleates randomly in the specimen.
