摘要：

Elastocaloric refrigeration based on the elastocaloric effect (eCE) is a promising solid-state replacement to the conventional vapor-compression one due to the environment-friendly and energy-efficient advantages. Here, a Heusler-type <111>-oriented Co49Fe3V33Ga15 superelastic alloy fabricated by the directional solidification method is designed showing large eCE around room temperature. Large adiabatic temperature change of 11.0 K upon fast loading is obtained at 290 K when the uniaxial pressure is perpendicular to the solidification direction. Moreover, the cycle stability of textured alloy is remarkably improved with respect to untextured counterpart. This work may inspire the discovery of newly promising elastocaloric materials for solid-state refrigeration. (C) 2021 Elsevier B.V. All rights reserved.
