A SPD process includes deforming metal material in an apparatus which comprises a material flow-through channel which is arranged in a first direction, and a press. The method also involves feeding metal material in the first direction so that the material need not be in a state of extreme stress, and pressing the material reciprocatively by the press in at least one second direction which is crosswise relative to the first direction, and deforming grain size of the material smaller. An apparatus for deforming metal material to SPD material. |
