High Temperature Flexural, Tensile Strength and Oxidation Behavior of Ti_3SiC_2 Ceramic at 900℃-1300℃ in Ambient Air

摘要

High temperature flexural and tensile strength of hot-pressed Ti_3SiC_2 ceramic were measured and analyzed from 900 to 1300℃ in ambient air atmosphere. The high temperature flexural and tensile strength are strong functionals of temperature. With the temperature increasing, the high temperature flexural and tensile strength decrease correspondingly. Moreover, the transition from brittle to plastic deformation was observed for both flexural and tensile testing. The oxidation behavior and oxidation mechanism were investigated.
