Physical and technical properties of alloys of the system W - BN

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Summary

  1. 1.

    A technique has been developed for the preparation of W-BN system alloys with various boron nitride contents.

  2. 2.

    Using x-ray diffraction, metallographic, and chemical analyses, a study was made of the character of reaction between tungsten and boron nitride over the temperature range 2060–2260°C; it was established that reaction between the components of these alloys leads to the formation of the following phases: a solid solution of boron in tungsten and the tungsten borides W2B andα-WB.

  3. 3.

    It is concluded that tungsten in contact with boron nitride is not suitable for engineering applications at temperatures of 2260°C.
