Colossal Elastocaloric Effect in Ferroelastic Ni-Mn-Ti Alloys

Physical Review Letters, 2019
Energy-efficient and environment-friendly elastocaloric refrigeration, which is a promising replacement of the conventional vapor-compression refrigeration, requires extraordinary elastocaloric properties. Hitherto the largest elastocaloric effect is obtained in small-size films and wires of the prototype NiTi system.

Orientation dependence of elastocaloric effect in Ni50Mn30Ga20 single crystals

Journal of Alloys and Compounds, 2021
Abstract In this study, the orientation dependence of the elastocaloric effect and superelasticity in Ni50Mn30Ga20 single crystals undergoing L21–10M/14M–L10 martensitic transformations was investigated. The maximum value of the adiabatic temperature change ΔTad at reverse stress-induced martensitic transformations was shown to weakly depends on the ...
