Recovery of severely deformed ferrite studied by in situ high energy X-ray diffraction

Recovery of severely deformed ferrite was followed in situ by High Energy X Ray Diffraction during heating and isothermal holding experiments. Dislocation densities annealing were determined a modified Williamson Hall method. The deduced recovery kinetics compared to post-mortem hardness measurements. A temperature dependent saturation exhibited holding. density drop behavior cannot be reproduced simultaneously the classical physically based models.
