Orientation Dependence of the Two-Way Shape Memory Effect in Single Crystals of Co35Ni35Al28Fe2 Alloy
The orientation dependence of the two-way shape memory effect (TWSME) in stress-induced martensite aged Co35Ni35Al28Fe2 (B2 + γ') single crystals has been studied. Aging leads to the stabilization of the oriented L10-martensite, which helps to induce the TWSME. By orientation variation of the single crystal, one can stabilize the twinned or detwinned martensite, which determines the regularities of the TWSME manifestation. In the aged [001] crystals, the twinned L10-martensite variant is stabilized. The TWSME in the [001] crystals develops with a large (−2.4%) reversible strain in the temperature range of 57–60 K and with a narrow (45 K) hysteresis, while the stabilization of the detwinned L10-martensite variant during aging in [110] crystals facilitates the development of a smaller TWSME value (−1.6%) in narrow ranges of 3–9 K, with a wide (79 K) hysteresis.
