Formation regularity of the phases in the nanometer powders of unlimited solid-solution alloys

Nanometer powders of three types of solid soluition alloy Bi Sb, Fe Cr and Fe Ni were prepared by gas evaporation process with induction current as the heating source. The formation regulation of the phases in the as prepared ultrafine powders as well as the morphology and structure of the particles were investigated. The results show that for this kind of alloy, the two components can also solid solution each other in their nanometer particles. In nanometer powders of Bi Sb and Fe Cr alloys, there formed solid solution phase (Bi,Sb) and α (Fe,Cr), but for Fe Ni alloy, phases α Fe and γ (Fe,Ni) formed in it's nanometer powders. The lattice parameter of the solid solution phase in nanometer powders continuously change with the composition of master alloys which also means that the components can unlimitedly solid solution each other.
