- 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 704°C for one hour. The image shows a mixture of recrystallised and deformed grains. There are some stacking faults (ribbon like contrast) in the recrystallised grains; austenitic stainless steels have a relatively low stacking fault energy.
