Abstract: Nano-amorphous (FeAl)1-xZrx (x = 20, 33.3) alloys have been prepared by mechanical alloying. The microstructure, morphology and thermal stability of as-milled powders were analyzed by XRD, TEM and DTA, respectively. The size of milled powders was smaller than 50 nm. The thermal stability of as-milled powders decreased with increment of Zr. The products of crystallization for milled powders annealed at temperature over the crystallization temperature were also investigated. The effective activation energies for crystallization are evaluated according Kissinger's plot. The composition range of amorphous (FeAl)1-xZrx was predicted from Miedema's theory and a geometric model.
