摘要：

Monolithic ZrB2, ZrB2-SiC, ZrB2-ZrC and ZrB2-SiC-ZrC were prepared by hot pressing in ternary ZrB2-SiC-ZrC system. They exhibited different microstructural features. Grain sizes of each phase were smaller in the ternary composites. Contour maps of mechanical properties were also plotted in ZrB2-SiC-ZrC ternary diagram based on experiments and software fitting. They established the relationships between chemical composition and properties in a visual way. Young's Modulus and Vickers hardness had linear relationships with composition, while the evolution of the strength and toughness was complicated. (C) 2015 Acta Materialia Inc.
