ORIENTATION DEPENDECNE OF STRESS HYSTERESIS
IN NiFeGa SINGLE CRYSTALS

The dependence of the stress hysteresis on orientation and test temperature in Ni 54Fe19Ga27 (at.%) single crystals was investigated in compression. The weak temperature dependence of hysteresis is observed at stressinduced martensitic transformation, which does not accompanied by detwinning. It is typical for 14Mmartensite regardless of the orientation and for L10-martensite in [001]-oriented single crystals. If process of
detwining is occurred, then the value of stress hysteresis is determined by test temperature and orientation.
Key words: thermoelastic martensitic transformations; superelasticity; stress hysteresis.
