- Further information
- This is a transmission electron micrograph taken at 200 kV, from a thin foil sample of "302AA" austenitic stainless steel. The sample was cold-deformed by rolling and then annealed at 704oC for one hour. The image shows recrystallised grains which which show uniform contrast because they are relatively free of dislocations, surrounded by a deformed matrix which has a high dislocation density. The recrystallised grain contains annealing twins (parallel bands with different contrast. The steps at the top left-hand corner are simply steps in annealing twin boundaries.
