Microstructure and Mechanical Property of (TiNbTaZrHf)C Synthesized by In-situ Reaction
文献摘要：
The (TiNbTaZrHf)C high entropy carbide(HEC) was successfully synthesized by complete commercial transition metal powders, obtained fine sintered bulks without additives by in-situ reaction element synthesis method. (TiNbTaZrHf)C bulk shows a face centered cubic rock salt structure with homogeneous single-phase FCC structure in composition and structure. The optimum sintering temperature is about 1900 ℃ at which the best mechanical properties are obtained. The mechanical properties of (TiNbTaZrHf)C ceramic block are better than those of binary transition metal carbides, and it has obvious high entropy effect. Adding a small amount of Al as sintering additive, the mechanical properties of (TiNbTaZrHf)C ceramics continue to improve, the bending strength of the samples at each temperature is increased by at least 38％, and the highest is 486 MPa. The elastic modulus and hardness of the sample at 1900 ℃ are also slightly increased by 4％ and 14％, respectively. The above conclusions illustrate that the properties of high entropy ceramics are greatly improved by in-situ reaction sintering.
