    Abstract

    The sinterability, microstructure, and mechanical properties of pure TiB2- and CrB2-doped ZrB2 prepared by spark plasma sintering were investigated. The solid solutions were synthesized by the complete borothermal reduction to form (Zr0.95Ti0.05)B2 and (Zr0.95Cr0.05)B2. The results showed that the solid solution of (Zr0.95Ti0.05)B2 yielded the smaller particle size than that of (Zr0.95Cr0.05)B2. The sinterability was also improved with the use of the solid solutions, as evidenced by an increase of relative density but at the cost of coarsened microstructure. Overall, (Zr0.95Cr0.05)B2 possessed significantly higher relative density and Vickers hardness than ZrB2 and (Zr0.95Ti0.05)B2.
