Popis: A new process has been developed to directly produce micrometer-sized fine Ni3Al powders from a chloride chemical precursor. The reaction can be carried out in several media, including the fused-salt medium described in this study. The Ni3Al powders produced from chloride precursors had an L12 structure and contained 0.5% excess aluminum over stoichiometry. Because of their small grain size, the particles may prove instrumental in improving the properties of intermetallic components, thus accelerating commercialization of nickel aluminide.
