Abstract

Neutron irradiation effects on bend strength of V/MgO and V/Al₂O₃ joints, which had been bonded at appropriate conditions, were studied to evaluate ceramic/metal joint for fusion materials using three-point bend test and fractography. Bend strength of V/Al₂O₃ joints was lowered by neutron irradiation, but that of V/MgO joints was not changed by neutron irradiation. It was considered that reduction of the strength of V/Al₂O₃ joints was not caused by the weakening of the interface, but caused by the formation of residual stress crack during irradiation.
