Coincidence of reciprocal lattice point (CRLP) model was used to predict the stable orientation relationships of metal/α-Al2O 3 hetero interfaces from geometrical considerations. The predicted stable orientation relationships (ORs) between various metals and α-Al2O3 agreed well with the experimentally observed ORs at the hetero interfaces fabricated by film growth processes. In the bcc metal/α-Al2O3 systems with different fabrication processes such as internal oxidation, Burgers and Pitsch-Schrader ORs were experimentally observed, which have not been predicted as the most stable orientation relationships by CRLP. However, these ORs are predicted in CRLP as secondary stable orientations.
