摘要

The microstructure, phase composition and interfaces of ZrB₂-30 vol%SiC eutectic were investigated using TEM fabricated via induction plasma spheroidization(IPS). The obtained ZrB₂–SiC hypereutectic consists of the alternating H–ZrB₂ and 6H–SiC lamellas, and its composition is ZrB₂-65.04 mol.%SiC. 3 types of interfaces including SiC lamella-ZrB₂ granule, ZrB₂ lamella-SiC lamella and ZrB₂ lamella-ZrB₂ granule present a preferential orientation relationship. High-resolution TEM observations show that the ZrB₂ phase in the eutectic prefers to growth along the (101) plane. In addition, the mechanical properties of each phase in the IPS-treated ZrB₂–SiC powder were measured by nanoindentation. Hardness and elastic modulus of ZrB₂ granules were measured 17.86 GPa and 168.97 GPa, respectively, while these values were obtained 9.99 GPa and 120.66 GPa for ZrB₂–SiC eutectic phase.
