Structures and hot deformation of Al–V2O5 mechanically alloyed composite

A very fine structure of mechanically alloyed Al–V2O5 composite was tested by means of transmission electron microscopy and X-ray energy disperse spectrum (EDS) analysis. Annealing of the composite was found to result in the intermetallic grains growth and an increase of the material porosity due to chemical reaction between components. Hot compression tests of as extruded and annealed samples confirmed high mechanical properties of the material at high deformation temperatures that result from very fine-grained and stable structure of the composite.
