Cu-Ta bulk nanocomposites with varying amounts of Ta were produced by high-energy ball milling followed by compaction and sintering. The final crystallite size of Cu and Ta during the high-energy ball milling depends on the deformation behavior of the Cu-Ta composite rather than the melting point of

Fully dense and single-phase Ti 2 AlC ceramic was successfully synthesized by a high energy milling and hot pressing using Ti, C and Al as starting materials. The effects of composition of the initial elemental powders and sintering temperatures on the purity and formation of Ti 2 AlC were examined.
MgTi, Mg 0.5 Ni 0.5 Ti and MgTi 0.5 Ni 0.5 alloys doped with 10 wt.% Pd were prepared by high energy ball milling and evaluated as hydrogen storage electrodes for Ni-MH batteries. X-ray diffraction analyses indicated that the Mg 0.5 Ni 0.5 Ti and MgTi 0.5 Ni 0.5 alloys could be monophased or compose
