Popis: A programme of work has been carried out to investigate the effects of thermal shock and thermal cycling on a range of reaction bonded silicon carbides (RBSCs). Thermal shock tests involved holding the samples at temperature for approximately 30 minutes before quenching in water held at 20°C. Room temperature four point bend flexural strength tests showed large reductions in strength for samples with down shocks (δT) in excess of 300°C. The damage was apparent as cracks, in some cases extending across the entire width of the samples.
