MICROGRAPHIC STUDY OF SLOW OXIDATION OF ZIRCONIUM (in French)

Journal Article · · Compt. Rend.
OSTI ID:4077509

Development of the oxide layer at 800--850 deg C on Van Arkel and zone- melted zirconium in slow oxygen at low pressures was studied. An indicated mechanlsm comprising preferential oxygen diffusion and subsequent saturation (29 at.%) at the grain boundaries, followed by oxide growth involving the entire grains, is discussed. Oriented needle patterns due to growth perpendicular to the grain boundaries at 850 deg C are illustrated. (TCO)
