摘要：

An attractive way to prepare ZrB2-ZrC-based composites at relative low temperature was proposed and confirmed experimentally. The thermodynamics calculations indicated the reaction between B4C and Zr2Cu was feasible at as low a temperature as 1100 degrees C. The experimental results showed that ZrB2-ZrC-based composites could be fabricated by heating Zr2Cu-covered B4C preforms to 1200 degrees C for 6 h in vacuum. Further, the microstructure features and mechanical properties were discussed. (C) 2011 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
