An investigation is reported cm the oxidation pMperties of alpha-zirconium ali 8WC in oxygen for exposures extending to 400 hr.-The kinetics were determined by volumetric and gravimetric techniques and may be represented for exposures to ~pproxin~ately 200 hr by the parabdic relationship: A$ = (2.1
The transition kinetics during linear to parabolic oxidation of chromium in H,O-H, gas mixtures have been measured thermogravimetrically. Based on a cation-deficit defect structure for Cr,Os, the transition follows a model llrst proposed by C. Wagner. Under conditions not far removed from the Cr, C
## Abstract In studies concerned with the oxidaβtion of metals various gas mixtures are used to establish the chemical potential of nonβmetallic components in crystals. CO/CO~2~ mixtures e. g. are used to estabβlish oxygen potentials at 1000Β°C; in the case of manganese it is found that the presence
