摘要：

Fracture toughness tests were carried out on Al-4%Mg/Al(2)O(3)p composites containing different sizes and volume fractions of alumina particulates. The results indicated that the fracture toughness was dependent on the interparticle spacing provided the particulate size was below a critical size. The critical particle size corresponds to the situation wherein the energy release rate on particulate cracking is sufficient to trigger dynamic unstable crack extension.
