Tailoring thermomechanical treatment of Ni-Fe-Ga melt-spun ribbons for elastocaloric applications

In the present work, the structural, mechanical and shape memory properties of Ni55Fe16Ga29 (at.%) melt-spun ribbons have been studied with a prospective of application in the elastocaloric devises. Particularly, a special thermo-mechanical treatment, consisting in the thermal aging under constant e...

Sumario:In the present work, the structural, mechanical and shape memory properties of Ni55Fe16Ga29 (at.%) melt-spun ribbons have been studied with a prospective of application in the elastocaloric devises. Particularly, a special thermo-mechanical treatment, consisting in the thermal aging under constant external stress, was elaborated to control the residual internal stress generated due to the melt-spinning processing and improve thermomechanical and superelastic responses of the ribbon. The stress-induced entropy change was evaluated for the ribbon with improved thermomechanical properties. (C) 2019 The Authors. Published by Elsevier B.V.
