When the fracture process involves cracks bridging, then brittle matrices may be toughened by ductile phases which dissipate plastic energy on deformation. Based on this premise, MoSi{sub 2}, despite its brittleness at low and intermediate temperatures, is currently under consideration as a high temperature material for structural applications where good creep resistance, and oxidation behavior are required. This paper investigates the effect of ductile and reinforcements (Ti-30Nb) on the toughness of MoSi{sub 2} based composite, and the interfacial reaction between the matrix and the reinforcements.
