Magnetostrictive inclusions in "non magnetic" metals and "magnetic memory" in magneto-plasticity: facts versus artifacts

Analysis and statistical treatment of the 200 scientific reports about magnetic field effects on plasticity of solids were performed. Thermodynamics criterions of the reversible and irreversible processes stimulated by magnetic field were applied for selection of the magnetoplastic effects of different origins. We focused on study of those magnetoplastic effects, where additional internal mechanical stresses are caused by magnetostriction of ferromagnetic inclusions. The cases of artifacts, when instrumental treatment of metals introduces ferromagnetic microparticles were verified and discussed.
