Thermoelectric prototypes for automotive applications have been already successfully demonstrated. However, according to car manufacturers, reducing cost and improving system sustainability and durability are the main challenges for this technology. Technological breakthrough of TEG design may allow reaching such expectations. We believe that “ring-shape”-TEG architecture is a good way to reach these goals.
This work presents different approaches (melt-based alloy fabrication, sintering and deformation processes) to deliver the desired shape of a p-type Zr0.44Hf0.44Ti0.12CoSb0.8Sn0.2. We investigate also the link between microstructure, composition and processing with the functional properties (especially their thermal conductivity that is currently too high). Prediction of nanostructured materials based on ab-initio calculation will be presented to give the good way of materials optimization.
