Abstract

This report describes the results of investigation to evaluate the relation between charpy impact strength and mechanical properties of brittle materials as SiC, Sialon, Al₂O₃, AIN, B₄C, WC-Co, TiC-TiN, Soda lime glass and Quartz glass. The charpy impact strength was obtained about the notched and unnotched specimens of these brittle materials. We analyzed correlation between the mechanical properties and charpy impact strength by the multiple regression method. The relation between microstructures of bending fracture surfaces and charpy impact strength of these brittle materials was also investigated.<BR>The results are as follows.<BR>(1) Charpy impact strength increased in order of WC-Co, TiC-TiN, Al₂O₃ and SiC.<BR>(2) The charpy impact strength showed close correlation with static bending strength of these brittle materials by the multiple regression methods.
