摘　　要：深冷处理作为传统热处理的补充能够提高材料的耐磨性、尺寸稳定性和综合力学性能,广泛应用于钢铁材料。近年来,深冷处理在铝合金方面的研究和应用取得了一些进展,本文对铝合金深冷处理方面的研究进展进行了系统的综述,重点分析了深冷处理在改善铝合金力学性能、尺寸稳定性和耐腐蚀性方面的宏观效果及其与处理工艺之间的关系,并从微观相组织、位错、晶格结构等不同尺度对微观组织方面的研究成果进行综述和分析,从而为铝合金深冷处理的研究和应用提供一定的指导。Cryogenic treatment is a supplement process of traditional heat treatment which can improve the wear resistance,dimensional stability andcomprehensive mechanical properties of materials. It has been widely used in steel. In recent years,fruitful achievements of cryogenic treatment on aluminium alloy have been obtained. The present work reviewed the research progress of cryogenic treatment on aluminium alloy systematically. The effects of cryogenic treatment on the mechanical properties,dimensional stability and corrosion resistance and their relationship with process were main analyzed. The research results of micro-machanism were also reviewed from different scales such as phase,dislocation and lattice structure. This work can provide some guidance for the study and application of cryogenic treatment on aluminium alloy.
