Beschreibung
Zusammenfassung:	FIELD: mechanics; devices made from memorized-shape effect materials; radio engineering; mechanical engineering; medicine. SUBSTANCE: method of control of actuating member made from ferromagnetic material of martensite transformation includes action of magnetic field of this member. Saturation magnetization of martensite is higher than that of austenite; action of magnetic field on actuating member is performed at temperature range of T>Tma(H=0), where Tma(H=0) is temperature of termination of martensite-austenite transition at absence of magnetic field H; change in magnitude of external magnetic field is selected sufficient for martensite transformation. Proposed method makes it possible to impart and shape to actuating member within limits of restorable compression, tensile, torsional and shearing strain due to use of polycrystalline material instead of monocrystalline material. EFFECT: enhanced efficiency. 5 cl, 4 dwg, 5 ex
