An overview of recent advances in ductile-phase toughening of multiphase intermetallics is presented. The fracture characteristics of aluminides, suicides, chromides, and their composites are reviewed to elucidate relationships between microstructure, toughening mechanism, and fracture resistance. The roles of crack-tip blunting, trapping, bridging, and interface delamination in instigating fracture resistance are considered. Prospects for improving fracture toughness are discussed in conjunction with relevant microstructural variables such as the volume fraction, size, morphology, constraint, and work-of-fracture of the ductile phase.
