The work is experimental. A structure of the martensite deformed steel was studied by TEM method. The dependence of scalar dislocation density on a size of fragments having different dislocation substructures in martensite steel was determined. It was established that a type of the dislocation substructure determines a character of the dependence of scalar dislocation density on fragment size. Physical reasons of this behavior was revealed.
