- Description
- Miscibility gap alloys (MGAs) are envisioned for use as thermal capacitors for the efficient storage and subsequent discharge of thermal energy. MGAs are created by combining non-reacting metals in a controlled micro-structure. In the investigated MGA, the fusible phase (copper) is enclosed inside an iron matrix. Upon heating the metallic constituents store energy in the form of sensible heat whilst increasing their temperature. Energy storage occurs at a fast rate due to the high inherent thermal conductivity of both metals. After exceeding the melting temperature of the copper, energy is predominantly stored in the form of latent heat while the fusible phase is liquefied. As a result, a very high volumetric energy storage density can be achieved. The current study presents a novel approach to manufacture Cu-Fe MGA using explosive compaction.
