Abstract
It is known that chromium influences the growth of an alumina oxide la yer on beta-NiAl at high temperatures. It has been claimed that oxidiz ed chromium will act as nuclei for the theta --> alpha-alumina phase t ransformation. This study presents RES-data on the presence of chromiu m in the oxide scale which tends to substantiate this claim. Also XRD results will affirm the above mentioned claim.
