Preparation of the Al-Cu-Co and Al-Cu-Ni Ternary Intermetallic Powders via a Solid-Liquid Reaction Ball Milling Technique

Al-Cu-Co and Al-Cu-Ni ternary alloy nanopowders were prepared via a self-developed solid-liquid reaction milling technique. The milling balls were made of the metals with highest melting point for each alloy systems. And the binary alloy melts of other two elements were used as raw materials. Formation regularities of Phases in the milling process were investigated and solid-liquid reaction mechanism of ternary alloy systems was discussed.
