| Abstract: | In this paper research progress in synthesis and properties of nanocrystalline Al and Al-Mg alloy is summarized. Synthesis of nano-crystalline Al and Al-Mg alloy by cryo-milling is reviewed in detail. Meanwhile,factors that affect the process of cryo-milling are analyzed and the influence of cryo-milling on the microstructure of nano-crystalline Al and Al-Mg alloy is also discussed. In addition,thermal stability of nano-crystalline Al is presented and evaluation. Research on their mechanical properties and creep resistance is reviewed in comparison with those of coarse-crystalline Al and Al-Mg alloy. |
