Description:
Although, SiC/SiC composites are very attractive for applications at high-temperature including advanced nuclear fusion/fission plants, their high material cost has been one of biggest issues to be utilized. In the neutron irradiation environments, high crystallinity of SiC fibers and matrix is essential to stabilize the mechanical properties, but the expensive crystallized SiC fibers may enhance the cost of material. As a potential option from the cost down aspect, utilization of amorphous SiC fibers was planned. This paper concerns about the radiation damage tolerance of SiC/SiC with amorphous SiC fibers as starting reinforcing fibers. The crystallization procedure of amorphous SiC fibers was investigated during thermal treatments, and a new NITE-SiC/SiC, called as IC-NITE (IC stands for "in-situ" crystallized), composite was produced. Its radiation damage behaviour and microstructural stability were examined by a heavy ion irradiation experiment and TEM.
