 note = {For the development of silicon carbide (SiC) materials for next-generation nuclear structural applications, degradation
of material properties under intense neutron irradiation is a critical feasibility issue. This study
evaluated the mechanical properties and microstructure of a chemical vapor infiltrated SiC matrix composite,
reinforced with a multi-layer SiC/pyrolytic carbon–coated Hi-NicalonTM Type S SiC fiber, following neutron
irradiation at 319 and 629 °C to ∼100 displacements per atom. Both the proportional limit stress and ultimate
flexural strength were significantly degraded as a result of irradiation at both temperatures. After irradiation at
319 °C, the quasi-ductile fracture behavior of the nonirradiated composite became brittle, a result that was
explained by a loss of functionality of the fiber/matrix interface associated with the disappearance of the interphase
due to irradiation. The specimens irradiated at 629 °C showed increased apparent failure strain because
the fiber/matrix interphase was weakened by irradiation-induced partial debonding.},
