摘　　要：综述了过去50年来铝合金中无沉淀析出带(PFZ)的研究,重点论述了PFZ的主要形成机理、影响因素及其对合金性能(主要为力学性能和耐腐蚀性能)的影响,系统介绍了PFZ在形成机理及对合金性能上所持的不同观点及其相关理论。最后,提出了对铝合金中PFZ方面存在的难点以及重点研究方向。Researches of precipitation-free zone(PFZ)in aluminum alloy over the past 50 years were reviewed and the main formation mechanism and influencing factors and the influence of PFZ on the properties(mainly mechanical properties and corrosion resistance)of the alloy were emphatically discussed.The different view points of the related theories of PFZ on the formation mechanism and properties of the alloy were systematically introduced.Finally,the difficulty and key research direction of PFZ in aluminum alloy were put forward.
