Enhancing functional stability of NiTi tube for elastocaloric cooling through overstress training

Tubular NiTi is a promising candidate refrigerant for eco-friendly elastocaloric cooling, but its severe functional degradation during cyclic phase transition (PT) is a key concern in the technology development. Here, plastic deformation of 6.7% is applied to NiTi tube by overstress training under 1...
