Abstract:

Continuous silicon carbide fiber-reinforced silicon carbide ceramic matrix composites (SiCf/SiC composites) are renowned for their exceptional mechanical properties, high-temperature stability, and irradiation resistance, rendering them ideal candidates for applications in the hot sections of aero-engines and nuclear reactors. The microstructure, properties, and application domains of these composites are significantly influenced by the fabrication routes employed. Among these, the nano-infiltration and transient-eutectic (NITE) process has gained prominence in the production of high-performance SiCf/SiC composites, attributed to its short processing cycles, high densification, and excellent irradiation resistance. This review provides a comprehensive summary of the principles and optimization strategies associated with the NITE process for SiCf/SiC composites fabrication. Furthermore, recent advancements in the high-temperature oxidation resistance, thermal conductivity, and irradiation resistance of SiCf/SiC composites produced via the NITE process are examined. The article outlines current progress and identifies remaining challenges in the industrialization of the NITE process, explores hybrid methodologies combining NITE with other fabrication techniques, and discusses future research directions and prospects for NITE-based SiCf/SiC composites.

Key words: SiCf/SiC composite, NITE process, ceramic matrix composite, mechanical property, irradiation resistance
