Nanocrystalline titanium aluminum powder, of composition Ti-48Al, was synthesized using a Fritsch planetary ball mill with a grain size of approximately 10 nm. The powder was compacted into cylindrical specimens with a relative density of 79% and subjected to uniaxial compressive loading at 600 °C in a mechanical testing machine. From these results, the deformation of nanocrystalline titanium aluminum is examined with relation to the applied load and the resulting grain structure. The results suggest a grain refining mechanism occurring during the deformation process.
