Fe base Phase Change Materials (PCM) for high temperature around 953–1273 K using multiple solid–solid transformations were developed. The amount of latent heat of PCM samples were measured by Differential Scanning Calorimetry. The amount of latent heat of Fe–xCo samples increased with increasing Co addition. The reducing atmosphere was suitable for the samples developed in this work. The durability performance of samples was confirmed by heat treatment experiments. From the viewpoint of heat accumulation/supply ability, cost and durability performance, Fe–Co(–Cr) system alloy is one of the most suitable Phase Change Materials for heat recovery from high temperature exhaust gases.
