      abstract     = {FeCrAl alloys are high temperature structural materials
                      with ever increasing technological importance, because in
                      the temperature range of 900-1300°C their resistance
                      against environmental attack exceeds that of other metallic
                      materials . This is due to the formation of a protective
                      alumina scale an the surface of FeCrAl-alloys during high
                      temperature service. During exposure at elevated
                      temperatures, the major life limiting factor for FeCrAl
                      alloys is the depletion of the alloy Al-content. In the
                      present work a number of commercial and model alloys have
                      been studied with respect to the lifetime oxidation
                      behaviour . The experimentally determined lifetimes were
                      compared with those calculated based an the available
                      lifetime prediction model. Analytical studies were performed
                      an oxidised alloys using a range of surface analysis
                      techniques to elucidate the oxidation mechanisms as a
                      function of exposure time and temperature. The results
                      demonstrate the importance of the minor alloying chemistry
                      for scale growth rate and adherence and consequently for the
                      service life of FeCrAl-based components . The observed
                      differences in oxidation rates between the studied
                      commercial materials and even between different batches of
                      one commercial alloy have been found to originate from the
                      interaction of typical minor alloying additions of the
                      reactive elements, such as Y, La, Ti, Zr and Hf with typical
                      alloy impurities of carbon and nitrogen. A major finding was
                      that for this reason, the optimum oxidation resistance can
                      not be achieved by one reactive element addition, but rather
                      by a combination of the latter. The exact amounts, type and
                      distribution of the reactive elements must be carefully
                      selected depending an the particular alloy application .},
