Abstract

A novel kinetics analysis method to quantifying the extent of metastable → stable Al2O3 phase-transformation in thermally-grown alumina scales is presented. This analysis involved assessing thermogravimetric data and the time dependence of the associated value of the instantaneous time exponent, n i. It was found that if there is θ → α transformation, the n i-value curve characteristically decreases to a minimum and then increases. The time corresponding to the minimum was defined as a transition time, t tr . It was found that after this t tr , the α phase was significantly established as a continuous layer and the overall scaling kinetics were greatly reduced. Furthermore, using a kinetics scenario for the θ and α co-formation, measured weight-gain kinetics could be well simulated from the initial co-formation stage to the steady-state single-α-phase-growing stage. Finally, it is shown that the transformation kinetics in the lateral direction can also be determined by this kinetics analysis method.
