Mechanical properties and oxidation behavior of a hot-pressed SiC-15-vol%-TiB/sub 2/ composite

Mark A. Janney

Abstract

The strength, fracture toughness, and oxidation behavior of a hot-pressed SiC-TiB/sub 2/ composite (with B and C additions) were investigated. Adding 15 vol% TiB/sub 2/ to an SiC matrix increased the mean strength and mean fracture toughness of the composite by 28% and 45%, respectively. Oxidation of the SiC-15-vol%-TiB/sub 2/ composite occurred slowly at 1000C and 1200C but was catastrophic at 1400C.
