摘要：

The fracture behaviour of particle-reinforced metal-matrix composites is shown to be controlled by a period of damage nucleation and evolution prior to final failure. The nucleation of damage can be by reinforcement fracture or decohesion and the mode of damage is shown to be controlled by the size of the reinforcement and segregation of alloying elements from the matrix, The nucleation and growth of damage can be monitored by a number of techniques, Acoustic emission and tomography are used here and the results are found to be consistent with simple models of void growth.
