Additive Fabrication of Shape Memory Alloys for Elastocaloric Devices

project information

project description

The use of Ni-Ti materials for elastocaloric applications in refrigeration systems is limited by the relatively poor heat transfer properties of commercially available bulk Ni-Ti. One promising approach to overcoming this limitation is the use of 3D printing to create lattice structures, which can dramatically increase the heat transfer surface area while simultaneously reducing the load-bearing volume. However, a significant challenge remains in optimizing both the additive manufacturing process and the post-processing parameters to achieve an optimal balance between thermal conductivity and mechanical strength. This study explores the potential of 3D-printed, architected Ni-Ti materials for enhancing elastocaloric performance in refrigeration systems, evaluating their feasibility for this specific application.
