Abstract: Features of formation of multilayer structure of composite with Al2O3 fibres and matrix of multicomponent alloys of iron and titanium was investigated. The composite was obtained by diffusion welding under pressure of a multilayer packet composed from foils of Fe- and Ti-alloys which were alternated with fragmented Al2O3 fibers. It is found that during the welding process of the packet at 1200°C for 45 minutes, a titanium alloy actively interacts with the oxide fibers. The alloy is based on iron, in contrast, was completely inert with respect to sapphire. The detailed examination of the data obtained by scanning electron microscopy and X-ray analysis is presented.
