Abstract

Si₃N₄ ceramics reinforced with SiC particles were fabricated via spark plasma sintering at 1650°C under 40 MPa pressure. AlN and Y₂O₃ were used as sintering additives. The purpose of this work was to study the influence of SiC powders on the properties of Si ₃N₄/SiC composites. The microstructure, phase composition, and mechanical properties of the composites were investigated. It was found that mechanical properties of the composites improved, the α-β transformation and grain growth of β-Si₃N₄ were inhibited and the equiaxed grain increased due to the increase of SiC _(w).
