      abstract     = {MAX phases have great potential under demands of both
                      high-temperature and high-stress performance, with their
                      mixed atomic bonding producing the temperature and oxidation
                      resistance of ceramics with the mechanical resilience of
                      metals.Here, we measure the mechanical properties up to 980C
                      by nanoindentation on highly dense and pure Cr2AlC, as well
                      as after oxidation with a burner rig at 1200 °C for more
                      than 29 h. Only modest reductions in both hardness and
                      modulus up to 980 °C were observed, implying no change in
                      deformation mechanism.Furthermore, micro-cantilever fracture
                      tests were carried out at the Cr2AlC/Cr7C3 and Cr7C3/Al2O3
                      interfaces after the oxidation of the Cr2AlC substrates with
                      said burner rig. The values are typical of ceramic-ceramic
                      interfaces, below 4 MPa, leading to the hypothesis that
                      the excellent macroscopic behaviour is due to a combination
                      of low internal strain due to the match in thermal expansion
                      coefficient as well as the convoluted interface.},
