Current state of the art thermoelectric (TE) materials are usually composed of expensive, scarce, or toxic elements. Ni and Ni based alloys, such as constantan, are consist of abundant elements and show relatively good power factor due to the high electrical conductivity. In this study, nano-sized precipitates were formed in the Ni based alloy by rapid cooling using a melt spinning method. The size and distribution of precipitates were controlled by changing the cooling and annealing conditions. The electrical conductivity, Seebeck coefficient, and thermal conductivity were evaluated. The effects of the precipitates and the small grain size on the TE properties were discussed.
