摘要	New Al-based nanocrystalline alloys containing dispersive nanoscale particles were prepared by adding appropriate amounts of Mm (misch metal) to Al-Fe-V-Si alloy. The microstructure, phase transformations and mechanical properties were studied in detail. It was found that with increasing Mm content the size of alpha-Al grains and particles decreased and alpha-Al-13(Fe,V)(3)Si particles existing in Al-Fe-V-Si alloys were replaced by metastable Al(8)Fe(4)Mm or quasicrystalline Al(20)Fe(5)Mm phase. It was found that the transformation of Al(8)Fe(4)Mm to alpha-Al-13(Fe,V)(3)Si phase is controlled by volume diffusion near 673 K. In addition, the materials exhibit 1.5-2.5 times higher tensile and fatigue fracture strengths in the nanocrystalline alloys than in Al-Fe-V-Si microcrystalline alloy as well as better thermal stability.
