Static Fatigue of a Siliconized Silicon Carbide

reportActive / Technical Report | Accession Number: ADA181479 | Open PDF

Abstract:

The static fatigue resistance of a novel siliconized silicon carbide has been evaluated. The material is fabricated by the in-situ reaction of silicon with fine, uniform carbon skeletons produced from liquid polymer solutions. The process has potential to make net shape parts without final machining. A very fine microstructure results which, in turn, gives high strength. Flexural specimens tested in this study had high strength at room and elevated temperatures up to 1300 C, and had good static fatigue and creep resistance. Keywords Mechanical properties Ceramic materials Silicon carbides Fatigue High temperature Static Fatigue Fractography.
