英文摘要	The ball milling process of 3Fe/xSi/(1-x) Al (x = 0.75, 0.5, 0.25) powder mixtures were studied by Fritsch Pulversitte 5 ball mill, scanning electron microscopy, and X-ray diffraction. Powders milled for 1h and 5h were annealed at 860°C for 4h and the phase constitutions of the annealed powders were investigated as well. The long range order parameter (LRO) was used to evaluate the degree of ordering of the ordered phase. The findings indicated that Fe (Si, Al) solid solutions can be produced after milling for more than 5h. The crystallite size of the solid solution milled for 5h is about 20 nm. The ordered phase of 3Fe/xSi/(1-x) Al (x = 0.75, 0.5, 0.25) powder mixtures milled for 5h and annealed at 860°C for 4h are Al0.3Fe3Si0.7, Al0.5Fe3Si0.5 and Al0.7Fe3Si0.3. The degrees of ordering of the three ordered phases are 0.7906, 0.6888 and 0.7302, respectively.
