Description
As a result of surface oxide dissolution during ball mill grinding of oxidized iron powder, spark plasma sintering (at temperature of 1000 °C and a pressure of 80 MPa), cold rolling with 88% reduction and recrystallization annealing at 1100 °C (0.5 h), bulk iron samples, containing strengthening FexO oxides of 3.2 nm in size, were obtained. It is demonstrated that without any alloying elements, except for air oxygen, recrystallized oxide dispersion strengthened iron specimens possess enhanced strength characteristics (yield strength and ultimate tensile strength of 570 and 632 MPa, respectively).
