Local precipitation phase inhomogeneity enables superior elastocaloric effects in additively manufactured NiTi alloys via in situ and post-heat treatment

Virtual and Physical Prototyping
NiTi shape memory alloys have been widely recognised for their functional properties, especially the elastocaloric effect. However, the elastocaloric performance is often limited by intrinsic phase transformation hysteresis.

The nematic susceptibility of the ferroquadrupolar metal TmAg2 measured via the elastocaloric effect

npj Quantum Materials
Elastocaloric measurements of the ferroquadrupolar/nematic rare-earth intermetallic TmAg2 are presented. TmAg2 undergoes a cooperative Jahn-Teller-like ferroquadrupolar phase transition at 5K, in which the Tm3+ ion’s local 4f electronic ground state ...

Elastocaloric effect of natural rubber

, 2016
Les effets caloriques représentent la capacité d’un matériau à voir son entropie varier sous l’effet d’une sollicitation externe et peuvent être utilisés pour des systèmes de refroidissement à l'état solide en remplacement (ou complément) des dispositifs traditionnels à base de fluides frigorifiques.

Elastocaloric effect in liquid crystal elastomers from molecular simulations

Liquid Crystals, 2018
ABSTRACTLarge-scale molecular simulations of the elastocaloric effect in swollen monodomain main-chain liquid crystal elastomers are performed, following the so-called ‘indirect approach’ where the magnitude of the effect is extracted from the system’s equation of state connecting stress, strain and temperature.
