Effect of large cold deformation after solution treatment on precipitation characteristic and deformation strengthening of 2024 and 7A04 aluminum alloys NING Ai-lin(宁爱林)1, 2, LIU Zhi-yi(刘志义)1... was achieved by relatively large cold deformation after solution treatment. STOLYARON et al[16] suggested that the G.P zones of main strengthening phase η′ didn’t heterogeneously nucleate......
at 350 °C, cold rolling with 60% thickness reduction and 250 °C annealing, successively. Key words: Mg-Li alloy; beryllium; scandium; solid solution strengthening ... up more energy. By this procedure, the final stage of annealing leads to recrystallization with fine grains. 3.2 Strengthening and grain refining by solid solution treatment After solution treatment......
