摘　　要：试验研究了不同稳定化退火温度对Al-6Mg-O.3Mn-0.13Sc-0.13Zr合金冷轧板材组织和性能的影响。试验研究结果表明:随稳定化退火温度的升高,板材强度下降而塑性升高,腐蚀抗力则先升而后降;合金板材经350T稳定化退火lh可达到强度、塑性和耐蚀性的最佳配合。The investigation was carried out on the effects of different stabilizing annealing temperatures on the microstructure and properties of Al-6Mg-0.3Mn-0.13Sc-0.13Zr alloy cold rolled sheets.The results show that with the increase of stabilizing annealing temperature,the strength decreases,the plasticity increases,and the corrosion resistance first increases and then decreases.The best combination of strength,plasticity and corrosion resistance can be achieved by stabilizing annealing at 350℃ for 1 h.
