Compared with that of 3Cr13 alloy, the oxidation resistance of the composites containing 5 vol.％TiC particle was improved greatly at 850℃, but the improvement was relatively limited at 950℃. But the oxidation resistance of 1Cr18Ni9 composites containing 5 vol.％ TiC particle was obviously improved at 950℃, and at 850℃ the improvement is not large. The TiC particle can improve the oxidation resistance mainly was by developing the oxidation selectiveness of the Cr element as to change the phase constitution of the oxidation film, to alleviate the production of the stress in the oxidation film and to improve the cohesive force of the oxidation film or matrix interface and the chemical combination of the oxidation film.

To assess the thermal contribution from oxidation reaction, the standard formation enthalpes of all reactants and products were used to calculate the oxidation enthalpies. It could be found that all oxidation reactions were exothermic. And oxidation played a more important role during the toluene trinitration at high temperature, because the reaction temperature of toluene trinitration is the higher than mononitration and dinitration, and the temperature coefficient of oxidation is higher than that of trinitration too.
