摘要：
Based on the recent improvement in mechanical properties of unidirectionally reinforced metal matrix composites (MMCs), SiC/Al and C/Al, impact property change due to neutron irradiation has been investigated. This paper details effects of neutron irradiation on fracture toughness of the MMCs. Materials used were formed sheets of SiC/Al and C/Al. Miniaturized Charpy V-notched specimens were tested by an instrumented Charpy impact tester. Neutron irradiation was performed in JMTR(LWR) at Oarai. The Charpy value was increased with increasing test temperature and with neutron irradiation. SiC/Al was rather more neutron fluence insensitive than C/Al and the insensitivity was correlated to differences in interfacial structure between the two systems.
