The annealing behaviour of the Fe-1.5%O steel with a grain size of about 0.2 μm was investigated using mechanical milling techniques. The structural analysis of the given samples was conducted using transmission electron microscope (TEM) at 200 kV. It is found that ultra fine-grained microstructure is stable during rapid grain growth at the temperature less than 800°C while heating to higher temperatures results in sharp grain coarsening.
