摘要

九方石是中温范围内应用最有效的热电材料之一。尽管如此，针对可扩展和快速合成方法的开发以及对这些化合物的机械性能的研究的努力较少。本文报道了先机械合金化（MA）后火花等离子烧结（SPS）制备的p型方晶石的力学性能。结果表明：经t <磨矿后，可形成单相方晶；SPS过程中二次相的出现提高了固结试样的显微硬度和抗维氏断裂能力。

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.
