摘要：
The reversible thermoelastic gamma-alpha' martensitic transformations under load in new single-crystal ferromagnetic Fe-28%Ni-17%Co-11.5%Al-2.5%Ti (at %) alloy have been studied. It is shown for the first time that precipitation of dispersed particles of the gamma' phase during aging for 7 h at 973 K induces the shape-memory effect and superelasticity in [001] single crystals of Fe-Ni-Co-Al-Ti alloy upon tensile strain. Superelasticity E >(SE) = 4.5-6% manifests itself in the temperature range T = 183-333 K.
