【 摘 要 】

Inter- and intragranular SiC-nanoparticle/Mg2Si composites were fabricated by plasma activated sintering, and the fracture toughness and thermoelectric properties were characterized. The toughness of the intragranular composite was 60% higher than that of pure Mg2Si. The electrical conductivity became lower compared with pure Mg2Si, however, it was independent of SiC content up to 5 vol%. Incorporation of a large amount of SiC nanoparticles within the Mg2Si grains is therefore an effective way to simultaneously improve toughness and thermoelectric properties. (C) 2018 Elsevier B.V.
