The Giant Elastocaloric Effect in a Cu-Zn-Al Shape-Memory Alloy: a Calorimetric Study

We study the giant elastocaloric effect in a Cu-Zn-Al shape-memory alloy by means of simultaneous calorimetry and dilatometry measurements under applied uniaxial compression which have been carried out with a bespoke experimental setup. The output data allow a unique quasidirect and indirect charact...
