Abstract
Three and four point bending tests were performed on SiC at room temperature in a controlled nitrogen environment on annealed and not annealed alumina and ferrite. The ferrite was also tested at 400{sup o}C in air. The Weibull moduli and characteristic strengths were determined from Weibull plots using a least squares analysis with a weighting factor. The Weibull moduli of the three and four point bending tests are in good agreement for the tested materials. Annealing of the alumina results in a higher Weibull modulus and lower characteristic strength. The explanation for the lower strength is probably that the compressive stresses in the surface layer which usually develop as a result of machining, are decreased by annealing. 10 figs., 1 tab., 12 refs.
