The Elastocaloric Effect in TiNi-based Foils
Materials Today: Proceedings, 2015 The elastocaloric effect in cold-rolled Ti49.1Ni50.5Fe0.4 foils of 30 μm thickness is studied by means of uniaxial tensile tests, digital image correlation and infrared thermography. During pseudoelastic cycling the evolution and orientation of Luders-like strain bands and the associated local release and absorption of latent heat depend on the rolling

Elastocaloric Effect Associated with the Martensitic Transition in Shape-Memory Alloys [PDF]
Physical Review Letters, 2008 The elastocaloric effect in the vicinity of the martensitic transition of a Cu-Zn-Al has been studied by inducing the transition by strain or stress measurements. While transition trajectories show significant differences, the entropy change associated with the whole transformation (\DeltaSt) is coincident in both kind of experiments since entropy ...
