DEPENDENCY OF MICROSTRUCTURE EVOLUTION AND MECHANICAL DURABILITY ON SINTERING TEMPERATURE OF W-SICF/SICM HYBRID COMPONENT

Reinforced silicon carbide matrix by silicon carbide nano fibers, her after SiCf/SiCm; is a promising materials for nuclear fusion applications, due to the engineering aspects of the SiCf/SiCm materials; related to its limited thermal conductivity and durability, it was indispensable to make cladding of SiCf/SiCm substrate by higher thermally conductive, durable material such as Tungsten. This article discussed the conditions of the processing to produce durable joining between tungsten and SiCf/SiCm by hot pressing technique. The article discussed the correlation between these conditions and the microstructure evolution of the product at the fusion layer. The correlation between microstructure evolution and mechanical properties of the produced hybrid component of W- SiCf/SiCm was studied as well.
