It is known that chromium influences the growth of an alumina oxide layer on β‐NiAl at high temperatures. It has been claimed that oxidized chromium will act as nuclei for the θ → α‐alumina phase transformation. This study presents RBS‐data on the presence of chromium in the oxide scale which tends to substantiate this claim. Also XRD results will affirm the above mentioned claim.
