Long-Term Stable Elastocaloric Effect in a Heusler-Type Co51V33Ga16 Polycrystalline Alloy

Abstract: Cyclic stability is of utmost importance for the long-term work of caloric materials in solid-state refrigeration. Heusler-type shape memory alloys show a large elastocaloric effect under low driving stress, but their intrinsic brittleness always leads to poor cyclic stability. Here, we demonstrate the simultaneously achieved large elastocaloric effect and long-term cyclic stability in a Heusler-type Co 51 V 33 Ga 16 polycrystalline alloy. Over a wide temperature range of 290−340 K, large adiabatic temperature… Show more
