Abstract

Dispersion strengthened materials belong into the group of composite materials, which are made mainly by powder metallurgy. Their structure has a polycrystalline matrix, in which dispersion particles are incorporated, mainly oxide, carbide and nitride type. The Al-C systems belong among modern materials designed for work at elevated temperature. This work focused on a study of the microstructure in containing 4 vol.% Al4C3.

The microstructure was analyzed X-ray diffraction line profile analysis. It is a powerful and convenient method to probe the microstructural characteristics of composites materials. In this paper the development of texture and size of crystallites in composite material dependence on annealing time and temperature was examined. Texture of the experimental materials was analyzed by means texture coefficient (TC). TC for the (220) plane in Al4C3 composite indicate the presence of markedly deformed texture. Size of crystallites depends on annealing temperatures and times.

Keywords.: X-ray diffraction (XRD); texture; crystallographic planes; size of crystallites
