中文摘要	Abstract ZrB2-20 vol% SiC composites added with 3 vol% Yb2O3 were hot-pressed at 1900 1C, and then heat-treated at 2000 1C in argon. The effect of heat treatment on phase composition, microstructure, and mechanical properties of the composites was investigated. Results showed that the high temperature heat treatment led to the depletion of Yb-containing phases by decomposition or evaporation, the formation of some pores at multiple-grain junctions, signi？cant microstructural coarsening with the increase of ZrB2 grain size from 1.9 mmto 4.8 mm, and the change of fracture mode from mixed inter/transgranular to fully transgranular. In addition, Vickers’ hardness, fracture toughness and ？exural strength were severely degraded after heat treatment. 2013 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
