Description
Summary:The effect of impurities in the iron powder on the physical properties of sintered magnetically soft materials was studied. Although vanadium increased the coercive force, it improved properties such as the saturation magnetization, specific electrical resistance, and hardness. The coercive force and bend strength of the powder materials were linearly dependent on the amount of carbide-forming elements. Phosphorous decreased this undesirable effect. Increasing the fraction of carbide forming elements in the materials decreased their densities, and increased their specific electical resistances, phosphorous being unable to change this dependence.
