Conclusions
The action of volume magnetic forces markedly surpassing volume gravitational forces on a disperse ferromagnetic system strongly intensifies the densification of the powder during sintering. The substantial improvement in physical properties exhibited by porous specimens after magnetic sintering indicates a higher degree of perfection of interparticle contacts, resulting from the intensification of densification achieved during sintering in a magnetic field, and, possibly, an anisotropic arrangement of powder in a magnetic field.
