Structural performance of ceramics in a high-fluence fusion environment

Creators

Description

The ceramics MgAl2O4, Al2O3 (single crystal), Si3N4, and a SiC/graphite laminate were irradiated to approx. 2 x 1026 n/m2 (E > 0.1 MeV) at 680 and 815K. Spinel exhibited near-zero dimensional change, while Al2O3 and Si3N4 swelled approx. 3 vol % and 1 vol % respectively. Strength of MgAl2O4 was increased, while strength of Al2O3 and Si3N4 were not greatly altered. The SiC/graphite composite, tested only at 680K, suffered almost complete delamination as a result of swelling of the SiC and densification of the graphite. These results are discussed in terms of microstructural alterations and related to various fusion applications
