N2  - The paper studies superelasticity in a 203–523 K temperature range of the 42.5Fe-34Mn-15Al-7.5Ni-1Ti at.% oligocrystals quenched and aged at 473 K for 3 hours. It is shown that the critical stress for the stress-induced α-γ' martensitic transformation slightly grows with the test temperature increasing in accordance with the Clausius–Clapeyron relation. The value of α = dσcr/dT characterizing this growth in quenched and aged oligocrystals, is close to 0.46 and 0.37 MPa/K, respectively. Regardless of the structural condition, superelasticity is observed within the whole mentioned temperature range. At room temperature, the maximum superelasticity is 6.0 and 6.8% of quenched and aged oligocrystals, respectively. A rapid degradation of the functional properties of oligocrystals is detected during the loading-unloading cycles at room temperature. After ten isothermal loading-unloading cycles, residual strain of 2.8 and 1.7% is observed in quenched and aged oligocrystals, respectively
