Abstract

High-resolution dark-field electron microscopy has been used to image antiphase domain boundaries (APB) in a commercial equiatomic FeCo alloy containing 2 wt.-%V. Direct measurement of antiphase domain size was carried out as a function of annealing time in the range 773–823 K. The domain size increased as a linear function of the square root of annealing time. The activation energy for domain coarsening was found to be 178 kJ/mol, which is lower than earlier estimates made using X-ray techniques.
