摘要
Elemental powders of Al-24. 4 % Fe (mole fraction) alloy were mechanically-alloyed using a conventional type ball-milling. Not only Fe particles gradually disperse in Al matrix but also Al and Fe crystal grains are refined to the order of ten nanometers after ball-milling for 180 h. The am0rphization starts at the early stage of ball milling and proceeds gradually. Complete amorphization is confirmed by ball-milling for 720h. The amorphization of the Powders after ball-milled for 180 h can be promoted by heating up to 673 K,which suggests a possibility of producing amorphous material by appropriate ball-milling and subsequent heating.
