摘要：

Nanocrystalline structure formation and properties of Al86Ni11Yb3 alloy were studied by DSC, X-ray diffraction, transmission and high resolution electron microscopy and microhardness measurements. The nanocrystalline structure was produced by annealing of the amorphous alloy at 473 K for different times. It consists of Al nanocrystals dispersed in an amorphous matrix. The nanocrystal size is about 10 nm. The average grain size of the nanocrystals increases slightly with annealing time. The microhardness of the nanocrystalline structure is higher than that of the initial amorphous alloy The microhardness increases to 4 GPa during the annealing. The fine structure of the nanocrystals and their mutual arrangement have been studied (C) 1999 Acta Metallurgica Inc.
