Hafnium oxidation rates at 760-mm oxygen pressure in the temperature range 350"-1200°C have been represented by logarithmic, parabolic, and linear-rate equations. The respective activation energies for the rate constants were 11.4, 36.0, and 26.1 kcal/mole. The value of the parabolic rate constant w
