Colossal Elastocaloric Effect in Ferroelastic Ni-Mn-Ti Alloys
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
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 ...

Elastocaloric Cooling of Additive Manufactured Shape Memory Alloys with Large Latent Heat [PDF]
The stress-induced martensitic phase transformation of shape memory alloys (SMAs) is the basis for elastocaloric cooling. Here we employ additive manufacturing to fabricate TiNi SMAs, and demonstrate compressive elastocaloric cooling in the TiNi rods ...

Cu‐Al‐Mn alloys are promising materials for industrial applications because of their excellent workability and low transformation stress. In this work, Cu‐Al‐Mn alloys with compositions in the range of 64.8–78.23 at% Cu, 12.2–31.6 at% Al, and 0–17.87 at% Mn were synthesized via arc melting, and their martensitic transformation temperature and latent ...

Magneto‐Tunable Thermal Diode Based on Bulk Superconductor
A thermal diode based on bulk superconducting materials is developed. Using the sharp change in thermal conductivity and its temperature dependence of Pb near the superconducting transition, Pb–Al junction works as a thermal diode with thermal rectification ratio (TRR) of 1.75. The working temperature can be tuned by applied magnetic field.
