| Abstract Scope |
Iron-Chromium-Aluminum (FeCrAl) alloys are promising candidate materials in many high-temperature applications due to their excellent oxidation resistance. Previous small-scale tests on pre-oxidized FeCrAl alloy at 1200C for 2 h have shown the efficacy of the alumina layer against carbon corrosion exposed to a 40-day long-term graphite exposure at 1000C. In addition, the pre-oxidize samples have been thermally cycled at various conditions under an ultra-high purity argon environment to assess whether the prescribed variations in temperature could affect the integrity of the developed oxide. The next step is to determine carburization rates through longer graphite thermal exposures (>100 days) at different temperatures for 5 to 200 days to assess the kinetics of carburization and the subsequent implications to the mechanical properties assessment of the FeCrAl. The talk would explore the carburization effect on the microstructure and mechanical properties of the FeCrAl under extreme conditions. |
