ABSTRACT
Internal oxides produced during the oxidation of Ni 2% Al in air at 1000°C have been studied with a combination of high resolution transmission electron microscopy and microanalysis of ion beam thinned samples. Acicular particles in the shape of rods and platelets of both Al2O3 and Ni Al spinels were examined from different regions of the internal oxidation zone. A variety of faults and defects were characterised in the spinel particles; and their possible role during the oxide development is discussed.
