Abstract
The structure and properties of steels produced from powders in a thermodynamically nonequilibrium state with an increased dislocation density, cellular substructure, and ground subgrains are studied. A non-equilibrium state of powders was reached using mechanical alloying of iron with carbon. Sintered steels inherited the powder structure, and the physicomechanical properties increased with increasing amount of added mechanical energy and carbon content. The strengthening mechanism is associated with the formation of a cellular dislocation structure in iron in its mechanical alloying with carbon.
