It has been found that a small percentage of chromium in recrystallized titanium carbide improves the resistance of this material to oxidation at elevated temperatures. The amount of oxidation was determined by the increase in weight of specimens of different chromium content after heating in air at 650°, 850°, 1200°, and 1400°C. The data obtained from these tests show that the maximum oxidation resistance, at each temperature, is obtained with an addition of 5 per cent chromium.
