The effects of sintering additives on irradiation swelling and modulus for monolithic NITE SiC was studied using 5.1 MeV Si2+ ion irradiation up to 5 dpa at 553-1273 K. The elastic modulus of NITE SiC decreased less than ∼7% in the highest damage case of 553 K, 3 dpa, indicating that the additives did not negatively affect the modulus of irradiated NITE SiC. A sample containing 9% additives showed higher swelling rates than high purity CVD SiC at lower temperatures. At 553 K, 5 dpa, the swelling of NITE SiC (9 wt.%) was twice as large as that of CVD SiC. Analysis of the electron diffraction patterns showed amorphization of the secondary phase, which is likely a primary reason for the increased swelling.
