| Popis: | The high-temperature oxidation kinetics at 800 to 1200 °C of as-cast heat-resistant HP40NbTi alloys produced by either static or centrifugal casting were studied by optical microscopy, electron microscopy, electron probe microanalysis, X-ray mapping, and thermogravimetric analysis combined with differential scanning calorimetry. The oxidation behavior of the as-cast HP40NbTi alloys was found to be complex physiochemical processes that are largely determined by the degree of the phase dispersion within the alloy and also by the temperature and exposure time. The oxidation rates of the alloys produced by different casting methods differed significantly. |
