| 中文摘要 | Solid refrigeration technology based on the elastocaloric effect has a great potential alternative to the conventional vapor compression cooling. Here we report the large elastocaloric effect in Ti-Ni (50 at%) shape memory alloy below its austenite finish temperature A(f) under different strain. Both Maxwell's and Clausius-Clapeyron equations are used to estimate the entropy change. The strain-induced entropy change increases with raising the strain and gets a maximum value at a few kelvins below A(f). The maximum entropy changes Delta S-max are -20.44 and -53.70 J/kg.K, respectively for 1% and 2% strain changes. Large entropy change may be obtained down to 20 K below A(f). The temperature of the maximum entropy change remains unchanged before the plastic deformation appears but moves towards low temperature when the plastic deformation happens. |
