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.
The movies have been provided for teaching purposes by Professor Hideharu Nakashima (ageigz@mbox.nc.kyushu-u.ac.jp) of Kyushu University, Japan.
