Abstract Recent developments in multiphase intermetallics are reviewed in this paper.The emphasis is placed upon the role various interfaces play in influencing the deformationprocess and mechanical behaviour of the multiphase alloys. The examples are taken fromTiAl based and (Ni,Fe,Co)Al based materials. It is shown that the operation of interface-related dislocation sources can improve the deformability of the brittle phases. A better balanceof mechanical properties can be obtained when the beneficial effects of the interfaces are manifested by a proper choice of constituent phases and conditions of material preparation andprocessing.
