Mechanical properties of p-type CeFe3.5Co0.5Sb12 and La0.75Ce0.25Fe3.5Co0.5Sb12 skutterudites synthesized by MA-SPS
Skutterudites are one of the most effective thermoelectric materials for applications in the medium-temperature range. Despite this, less efforts were targeted on the development of scalable and fast synthesis method as well as on investigation of mechanical properties of these compounds. In this work we report on mechanical properties of p-type skutterudites obtained by mechanical alloying (MA) followed by spark plasma sintering (SPS). It is shown that a single-phase skutterudite can be formed after milling for t < 30 min. Appearance of secondary phases during SPS enhances microhardness and Vicker’s fracture resistance of the consolidated samples.
