Transformation of Co–Ni–Al single crystals in tension
نویسندگان
چکیده
We present for the first time pseudoelasticity and shape memory results on Co–Ni–Al single crystals in tension. The experimental transformation strains approached 6% in tension in the [115] orientation. Despite the considerable volume change (0.0447), the transformation exhibits remarkable pseudoelasticity and shape memory recoverability in tension. A theoretical treatment is presented to explain the tension compression asymmetry in the stress–strain response, the change in transformation hysteresis with stress, and the role of secondary phase on the transformation temperatures. 2005 Acta Materialia Inc.

Pseudoelasticity in Co–Ni–Al single and polycrystals
The pseudoelastic responses of heat-treated CoNiAl single crystals with [001] and [115] orientations, multicrystals of nominally [123] orientation, and polycrystals are investigated under tension and compression stress states. The highest transformation strains are found under pseudoelasticity for the [001] orientation in tension and compression as 6.2% and 4.1% respectively. Experiments reveal...
متن کاملCompressive Response of A Single Crystalline CoNiAl Shape Memory Alloy
The effects of crystallographic orientation and temperature on pseudoelasticity and recoverable strain levels under constant stress are revealed for the Co-31at.%Ni-27at.%Al alloy single crystals under compression. The single crystals demonstrate a perfect pseudoelasticity at temperatures as high as 170 °C, recoverable transformation strains of 4% along the [100] orientation and 2.5% along the ...
متن کاملExperimental Study on the Magnetomechanical Characteristics of Ni-Mn-Ga Ferromagnetic Shape Memory Alloy Single Crystals
Magnetic shape memory properties of Ni-Mn-Ga single crystals were characterized by measurement of stress-induced martensite reorientation under constant magnetic fields. Also magnetic field-induced strain as a function of the applied magnetic field under different constant compressive stress levels has been investigated. All the experiments were performed at room temperature in which the sample...

Magnetic and Electrical Resistivity Study of Electroless Amorphous Ternary System (Ni-Co-P) show a qualitative dependence of crystalline phases formed during transformation on the annealing temperature and composition. Electrical Resistivity values increases with increase in cobalt content and samples with higher resistivity show lower temperature coefficients. The Initial increase in magnetiza...
متن کاملThe crystal structure of thermally- and stress-induced Martensites in Ni2MnGa single crystals
Deformation behavior of Ni~mnGa single crystals uniaxially loaded in compression and tension along the (100) p j and 1110) pj axes were investigated. It was shown that three successive stress-induced structural transitions may be observed for specimens tensed along Ihe
