Processing and mechanical properties of a porous low carbon steel with a controlled porous structure by imposition of a static magnetic field

Porous low carbon steels with a controlled porous structure were processed by imposition of a static magnetic field, and mechanical properties were investigated. Rotation behaviors of a low carbon steel in a static magnetic field was investigated by a theoretical analysis. The derived rotation time well agreed with the experimental result. The porous low carbon steel, which is the sintered green compact filled into a carbon die with a magnetic field, showed orientated structure parallel to the direction of a magnetic field. Compressive properties of the porous low carbon steel with a magnetic field showed higher collapse stress and higher densification strain compared with those of the porous low carbon steel without a magnetic field. Modifications of the compressive properties might be attributed to the oriented structure of the porous low carbon steel due to imposition of a static magnetic field.
