摘要
En 中文
This study focuses on tailoring commercial Nitinol, the most commonly used elastocaloric material, for near-room-temperature cooling applications. Short heat treatments near 500 degrees C were used to fine-tune the material's transition temperature, resulting in austenite finish temperatures ranging from 6.0 to 25.5 degrees C and altered superelastic and elastocaloric properties. Plateau stresses decreased while temperature changes rose from 21.5 degrees C up to 27.9 degrees C at 6% strain. Significant variability in the Nitinol response when testing below its austenite finish temperature was observed. The effect of mechanical cycling on transition temperatures was also evaluated, demonstrating an increase for all the samples.
