THERMAL TREATMENT OF MONOCRYSTALS OF Fe-Ni-Co-Al-Ti FERROMAGNETIC ALLOY WITH SHAPE MEMORY EFFECT AND SUPERELASTICITY ORIENTED IN 001 DIRECTION AT STRETCHING STRAIN

摘要

FIELD: metallurgy.;SUBSTANCE: invention can be used for production of actuators, transducers and dampers. Proposed method comprises homogenising annealing of Fe-Ni-Co-Al-Ti ferromagnetic alloy monocrystals including the following components, in wt %: Fe - 42.8, Ni - 30.7, Co - 18.4, Al - 5.8, Ti - 2.3 in atmosphere of inert gas He at 1250°C 10 hours, heating and holding at 1280°C for 1 h with subsequent quenching in water of room temperature and ageing in atmosphere of inert gas He at 600-700°C for 1-7 hours with subsequent cooling in water.;EFFECT: shape memory effect and superelasticity.;1 tbl, 1 ex
