Enhanced Mechanical Properties of Alumina by Dispersed Titanium Diboride Particulate InclusionsJournal of the American Ceramic Society
AbstractThe mechanical properties of composite ceramics composed of 0 to 20 vol% of titanium diboride particles dispersed in an α-alumina matrix were investigated. The alumina-titanium diboride composite powder was hot-pressed at 1470⁰C for 20 min to achieve over 98.8% of the theoretical composite density. The strength and fracture toughness of the twophase, hot-pressed composite were both significantly improved compared to the single-phase alumina. Results from different methods of measuring the stress intensity factor, (KIC) are compared and discussed.
