Compressive Response of A Single Crystalline CoNiAl Shape Memory Alloy
نویسندگان
چکیده
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 [123] orientation, small stress hysteresis (<40MPa) and high strength level against dislocation formation.

Constitutive law for shape-memory alloys subjected to multi-axial loading, which is based on a semi-micromechanical integrated multi-plane model capable of internal mechanism observations, is generally not available in the literature. The presented numerical results show significant variations in the mechanical response along the multi loading axes. These are attributed to changes in the marten...
