Effect of orientation on the high-temperature superelasticity in Co49Ni21Ga30 single crystals Academic Article uri icon

abstract

  • The temperature interval ΔT SE of superelasticity in [001]-, [123]-, and [124]-oriented Co40Ni21Ga30 (at. %) single crystals strained at compression has been studied. It is established that ΔT SE in the [001]-oriented single crystal amounts to 441 K and the reversible B2-L10 martensite transformations in loaded samples take place at T 2 = 698 K. In [123]- and [124]-oriented samples, ΔT SE decreases to 233 K and the superelasticity is observed up to T 2 = 523 K. © 2009 Pleiades Publishing, Ltd.
