| Abstract | Al-6Mg-0.4Mn-0.2Sc-0.1Zr-0.1Cr (mass fraction, %) alloy was prepared by vacuum induction melting, and the microstructures and mechanical properties of cold worked samples annealed at 350, 400, 450 and 500 degrees C for 1 h were investigated. TEM observation indicated that tangled dislocation cells are typical microstructure in cold worked sample; After 350 degrees C annealing, the dislocations arrange regularly and the density decreases sharply, the alloy recovers partly and the grain size is about 500 nm; Further annealing to 500 degrees C, recrystallization proceeds gradually in a wide temperature range due to the Zener drag effect of Al-3 (Sc, Zr) phase. As a result, the mechanical property changes greatly at 350 degrees C but keeps steady with further temperature increasing. |
