- W2095060467 abstract "Toughening of ceramic materials by using a bimodal grain size distribution has already been mentioned early in literature. This kind of toughening can be explained by an interlocking of the large grains during crack propagation. This so called bridging can operate very effectively for large grain size ratios and large aspect ratios of the coarse grained phase. In this approach ultrafine particles have been used to produce the bimodal grain size distribution. The main advantages over conventional powders is that large coarse grained powders can be densified. Then the established microstructure reveals a large grain size ratio. Furthermore the defect size which is correlated to the size of the largest grains is still quite low and hence high strength values can be expected. As starting powders mixtures of ultrafine SiC powder (particle size below 20 nm) and 10 or 20% coarse grained α-SiC powder with a particle size of 10 μm were used. These mixtures and pure ultrafine powders were Hot Isostatically Pressed (HIPed) at low temperatures (below 1700°C) and high pressures (350 MPa). At 1500°C densities above 90%TD and at 1600°C above 95%TD could be achieved. A microstructural evaluation shows that the ultrafine powder particles exhibit large grain growth but still remain in the submicron range. The large particles show only a negligible coarsening. The resultant large grain size ratio larger than 10 leads to a significant increase in fracture toughness. While the fine grained SiC without addition of coarse grained SiC shows fracture toughness values of about 4.5 MPam12, the addition of 10% coarse grained powders leads to increase of fracture toughness of about 10%. SiC samples with 20% of coarse grained powders even reach K1c values of 6 MPam12." @default.
