Abstract

The paper studies the effect of heat treatment modes and uniaxial tension on the magnetic properties, internal stress and specific resistance of 50Ni2Mo powder steel. It is shown that when treated and mechanically loaded in the elastic range and weak magnetic fields, the steel reveals anomalous behavior of its magnetic characteristics such as coercive force, maximum permeability and residual induction. The observed anomalous behavior is analyzed in the framework of physical mesomechanics and is associated with porosity of the powder material. It is demonstrated that physical mesomechanics and magnetic measurements hold promise as an efficient tool of research in porous ferromagnetic materials in various effective external fields. The thus studied magnetic characteristics allow efficient control of heat treatment modes of 50Ni2Mo powder steel.
