摘要：
A novel amorphous Al70Fe25Zr5 alloy was synthesised through high energy ball milling the mixtures of Al, Fe and Zr powder with the milling intensity of 150G (G is the gravitational acceleration). By comparing with the binary Al-Fe amorphous, differential scanning calorimeter results indicated the crystalline temperature of ternary Al70Fe25Zr5 amorphous alloy shifts higher temperature, and it showed two stages of crystalline reactions which corresponded to the formation of Al5Fe2 and Al3Zr phases respectively. Improvement of the thermal stability for this novel Al70Fe25Zr5 amorphous alloy is explained in terms of the total structure factor that was determined by the X-ray diffraction method.
