Abstract
The resistance changes produced by thermal treatment of Fe3Al have been measured and the annealing kinetics analysed. It was found that an increase in long-range order produced a large decrease in resistance. It was found that the rate at which ordering takes place is a function of the initial quenching temperature. All curves were fitted to the standard rate equation giving an order of reaction n=2.2 for specimens quenched from 620°c and n =1.5 for specimens quenched from 530°c. The activation energy obtained from resistivity kinetics was found to be much lower than the mean activation energy for diffusion.Keywords
