NANOSTRUCTURED MULTI-COMPONENT MATERIALS BY MECHANICAL ALLOYING

We have shown that nanostructured multi-component materials like TaC, Nb₇₈Ge₂₂, Mo₇₀Si₂₀B₁₀, Mo₆₀Os₂₀B₂₀, Ru₅₂Zr₆B₄₂, (NbC)₂₀Co₈₀ and (WC)₈₀-(Ti₉₀Cu₁₀)₂₀ with an effective length size reduced to atomic level (a few nanometers) can be produced by mechanical alloying of the elemental and/or alloy powders in a high-energy ball mill. All process steps and samples preparation for characterization were done under glove box conditions.
