Abstract
Quarternay carbides of Ti₃Al_xSi_1-xC₂ (x=0.3, 0.5, and 0.7) were oxidized at 400, 600, and 800 °C for 0.5-6 months in order to study their long-time oxidation behavior in air. When they were oxidized at 400-600 ^oC for 0.5-3 months, oxidation proceeded relatively slowly with moderate weight gains. However, further oxidation..... More
