Accelerated learning and co‐optimization of elastocaloric effect and stress hysteresis of elastocaloric alloys

Rare Metals
Abstract The development of high‐performance advanced elastocaloric alloys is crucial for the implementation of elastocaloric refrigeration. Here, we present a machine learning (ML) framework to accelerate the development of novel elastocaloric alloys with large adiabatic temperature change (Δ ...

Elastocaloric and Piezocaloric Effects in Lead Zirconate Titanate Ceramics

Energy Technology, 2016
AbstractThis study demonstrates that stress‐driven caloric effects can be obtained in bulk lead zirconate titanate (PZT) ceramics. The strain and polarization gradient have been utilized to determine the elastocaloric and piezocaloric effects, respectively.

Elastocaloric effect in poly(vinylidene fluoride-trifluoroethylene-chlorotrifluoroethylene) terpolymer

Applied Physics Letters, 2016
The elastocaloric properties of poly (vinylidene fluoride-trifluoroethylene-chlorotrifluoroethylene) [P(VDF-TrFE-CTFE)] terpolymer were directly characterized using an infrared imaging camera. At a strain of 12%, a reversible adiabatic temperature variation of 2.15 °C was measured, corresponding to an isothermal entropy variation of 21.5 kJ m−3 K−1 or ...
