摘要：

研究深冷轧制、室温轧制和后续退火对6082铝合金析出相、显微组织演变（回复,再结晶与晶粒生长）、力学性能和腐蚀行为的影响。采用差示扫描量热仪、透射电子显微镜和背散射电子衍射研究深冷轧制、室温轧制及后续热处理样品的析出动力学和显微组织形貌,以探讨其力学性能。经200°C退火后,深冷轧制样品的抗拉强度和硬度（345 MPa和HV 127）比室温轧制样品的抗拉强度和硬度（320 MPa和HV 115）更高。200°C退火后深冷轧制样品抗拉强度和硬度得到提高是因为铝基体中析出β''相,与室温轧制样品相比产生更大的Zener阻力。与室温轧制样品的腐蚀和点蚀电位（-1.335 V和-710 mV）相比,深冷轧制样品的腐蚀和点蚀电位（-1.321 V和-700 mV）也得到提高。深冷轧制样品具有较高的位错密度,Mg4Al3Si4析出相溶解到基体中,通过形成钝化保护层和抑制原电池的形成,使样品的抗腐蚀性能得到提高。
