a Specific mass-gain curves of the CCAs under investigation and three CCAs from the literature (provided for the sake of comparison), b–d SEM-energy-dispersive X-ray spectroscopy (EDXS) analysis revealing the surface morphology and oxides of the AlTiVCr CCA after exposure at 700 and 900 °C for 24 h, and e–g SEM-EDXS analysis of the Al0.9FeCrCoNi CCA after exposure at 700 and 900 °C for 24 h. Note (1): The phases designated in the SEM micrographs were identified using EDXS and X-ray diffraction (XRD). Note (2) some irregularities such as small weight losses were observed in the mass gain curves which could be due to scale spallation.
