Elastocaloric effect associated with the martensitic transition in shape-memory alloys

E Bonnot, R Romero, L Mañosa, E Vives, A Planes - Physical review letters, 2008 - APS
The elastocaloric effect in the vicinity of the martensitic transition of a Cu-Zn-Al single crystal
has been studied by inducing the transition by strain or stress measurements. While …
