Abstract
Amorphous Al65Fe20Zr15 alloy has been prepared by mechanical alloying. The as-milled powders were analyzed by XRD and DTA. The fully amorphous alloy was identified by the hallo rings of XRD pattern. The effective activation energy of crystallization was estimated with modified Kissinger’s plot and it is 321.0 kJ/mol evaluated from the peak temperature of crystallization. The product phases of crystallization composed of Al3Zr, Al82Fe18, AlFeZr and an unidentified phase. The crystallization kinetics was also discussed by using the isochronal DTA scans and the values of corresponding kinetic parameters were determined.
