Preparation of the Al–Cu–Fe & Al–Fe–Si ternary intermetallic powders via a novel reaction ball milling technique

Abstract The synthesis of elevated-temperature intermetallic powders such as the ternary Al–Cu–Fe and Al–Si–Fe alloy powders was carried out using a novel solid–liquid reaction milling technique. In comparison with that of high-energy ball milling, the phase formation law of ternary alloys by this technology was studied. Moreover, the reaction mechanism and advantages were discussed.
