| Abstract Scope |
The elastocaloric effect results from the reversible solid-to-solid martensitic phase transformation, allowing for the implementation of such materials in refrigeration devices with high efficiency and environmental protection. Current state-of-the-art cooling technologies use liquid refrigerants to provide the necessary cooling power, however, these liquids produce hazardous byproducts and release carbon dioxide into the atmosphere contributing to air pollution. Copper-based shape memory alloys have shown promise demonstrating competitive properties while accessible at a low cost and less energy-intensive fabrication methods, eliminating the need for harmful liquid coolants. This study investigates the Cu-Al-Mn-Ni system by conducting a series of high throughput experiments guided by Bayesian optimization to develop an alloy suitable for elastocaloric cooling applications. |
