A Nb-19 at%Al alloy, which composed of Nb3Al-phase and a small amount of Nb-phase, was heated in a technical-grade nitrogen and in an artificial air at a rate of 2°C/min up to 1000°C. The reactions were compared with those in pure nitrogen, on which a paper has already been published.<br>In both gases weight increase started at ca. 800°C, as did in pure oxygen. The weight increases at 1000°C were, however, ca. 10% in the nitrogen and ca. 40% in the artificial air respectively of that in the oxygen.<br>In the case of the nitrogen, major components of the scale were oxides, although nitrogen compounds were detected in the X-ray diffraction pattern (XRDP). The major reaction was considered to be the oxidation caused by oxygen and moisture in the nitrogen, whose process was identical with that in the oxygen.<br>In the cases of the air, no nitrogen compound was detected in XRDP, although the surface was in a color specific to reactions in nitrogen. The reaction was considered to be akin to that in the oxygen. A comparison with the reaction in Ar-20 vol%O2 revealed nitrogen retarding the reaction.
