Article Synopsis
- The paper investigates the elastocaloric effect of two shape memory alloys, CuAlZn and CuAlMn, under compression at room temperature, analyzing their temperature changes during unloading.
- During adiabatic testing (0.1 s(-1) strain rate), CuAlZn showed a higher temperature change of 4.0 K compared to 3.9 K for CuAlMn, despite CuAlMn having a significantly lower maximum stress of 120 MPa at 4% strain.
- The latent heat values determined for CuAlZn and CuAlMn were 4.3 J/g and 5.0 J/g, respectively, with CuAlMn yielding a higher potential coefficient of performance (COPmat) of approximately 13
