    Abstract

    An amorphous phase with blend composition of Al85Co15 was fabricated by mechanical alloying (MA) from the mixture of pure Al and monoclinic Al13Co4, which cannot be obtained by MA for the Al and Co elemental powders. Use of the MA from the compound and element is a result of the enhancement of efficiency during milling by leaving out the welding and supressing the agglomeration of the powders in the process. Mechanism of the amorphization is discussed together with the mechanical grinding of the compound. We assert that the MA between the Al and compound is an available process to produce amorphous phases in Al-enriched (Al > 85 at.%) alloys.
