Motion of Dislocations at Elevated Temperatures

H. K. D. H. Bhadeshia

The movies, which are in MPG format, show the movement of dislocations in ferritic steels (body-centred cubic crystal structure), at elevated temperatures. The images are taken in a hot-stage in a transmission electron microscope. These observations have been used to conclude the molybdenum and tungsten have the same solid-solution strengthening effect on ferrite.
