amorphous powders were prepared by a mechanical alloying process.The phase structure

microstructure and thermal stability of the powder under different milling time were analyzed by X-ray diffractometry

differential scanning calorimetry and scanning electron microscopy.The results indicate that Al

amorphous powder can be prepared by mechanical alloying.With milling for 100 h

the powder basically presents amorphous state.The thermal stability of the alloy powder is increased with the increase of the ball milling time

and the overall performance shows that the exothermic peak is shifted to the right

further confirming the formation of the amorphous phase.
