Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

  1. 1.

    The optimum conditions for the preparation of a composite material of the ZrB2-SiC-C-V system by the hot-pressing method have been determined. In the system investigated a liquid phase forms in the temperature range 1900–2000°C.

  2. 2.

    The vanadium-containing composite material was found to consist of the following phases: ZrB2, ZrC, VB2, SiC, and C.

  3. 3.

    A study was made of the oxidation resistance of materials of the ZrB2-SiC-C, ZrB2-SiC-C-Nb, and ZrB2-SiC-C- V systems in the temperature range 1200–1800°C. The highest oxidation resistance was found to be exhibited by a material of the ZrB2-SiC-C-V system.
