Description/Abstract

A MoSi2/Nb composite with ellipsoidal reinforcements has been produced by uniaxial forging of a sample manufactured by hot isostatic pressing (HIP). The final aspect ratio of the reinforcing Nb particles as a function of strain has been predicted. Reaction products at the interface have been identified by means of energy dispersive X-ray analysis, electron diffraction, high resolution electron microscopy and image simulations. Substantial improvements have been obtained in the fracture toughness compared to the unreinforced matrix and MoSi2 reinforced with identical volume fraction of spherical Nb reinforcements. The increase has been interpreted on the basis of a reduced number of particles that totally debond.
