Abstract
A melt spinning technique followed by spark plasma sintering technique was used to synthesize nanostructured SrSi2 alloys with high homogeneity and density (>99 %). The impact of the wheel speed on the microstructure of the ribbons was investigated and shows the presence of nanostructures. After sintering, typical grain size between ∼140 and ∼400 nm was obtained. We show that they permit to decrease strongly the lattice thermal conductivity. The ZT values of these melt-spun alloys are about two times higher than in our bulk material. We finally show that this short step process could be of strong interest for further development.
