Thermoelectric power studies of copper precipitation in a new interstitial-free steel

Copper precipitation has been tracked through thermoelectric power measurement in a copper-containing interstitial-free steel. The amount of copper in solid solution and the nature of the precipitates modify the thermoelectric power of ferrite. The change in thermoelectric power due to different substitutional alloying elements in solution in ferrite suggests a dependence on the atomic size difference of the element with iron.
