Physical properties of Ni-Mn-Ga polycrystals were investigated in details. Temperature dependences of the magnetostriction and impedance were studied. The measurements of an impedance can be used for the control of a magnetic state in magnetostriction studies. Ferromagnetic ordering of austenite give rise to large magnetic field induced strain in martensitic phases of Ni-Mn-Ga alloys. This phenomenon is worthy for the practical application. Influence of ferromagnetic state of austenite of Fe-Ni-Co-Ti alloys is positive for the practical goal. As shown experimentally, ferromagnetic ordering with cold-working treatment of austenitic specimens of Fe-Ni-Co-Ti alloys leads to improvement theirs properties as shape memory materials.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
