摘要	Influence of intermediate annealing temperatures on the strength of repeatedly cold-rolled Al-Mg-Sc-Zr alloy was investigated. It is indicated that the strength of the alloy has no obvious change with intermediate annealing at 400 degrees C for 1 h, but it decreases significantly with the increase of rolling passes after intermediate annealing at 450 degrees C for 1 h, especially for the yield stress. High density of dislocations induced by cold-rolling will provide a fast diffusion path for Sc and Zr atoms and promote coarsening of the Al(3)(Sc, Zr) particles when samples are annealed at higher temperature. As a result, Al(3)(Sc, Zr) particles have weak abilities to hinder the movement of dislocations and recovery process of the alloy, which make the strength of the alloy decrease.
