Abstract

Ultrahigh-temperature Ta4ZrC5–xZrB2 composites were prepared from mechanically activated Ta–Zr–C–B mixtures by electrothermal explosion under pressure and characterized by XRD, SEM, and metallographic analysis. Special attention was given to the impact of mechanical treatment duration. Synthesized composites represented finely (<2 μm) dispersed Ta4ZrC5 in a ZrB2 binder with a residual porosity of 8–10% and HV around 21 GPa. Our results may turn interesting to those engaged in R & D of refractory fine-grained ceramic composites.
