Characteristics of the manufacturing technology of dense parts from, and the mechanical properties of, some hexaborides of the rare-earth metals

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

Summary

  1. 1.

    On the basis of the investigation described, a study was made of the regularities of hot pressing and the mechanical properties of lanthanum, samarium, europium, and dysprosium hexaborides.

  2. 2.

    Dense components, with a density approaching the theoretical one, from LaB6, SmB6, EuB6, and DyB6 can be produced by hot pressing at temperatures of 2223–2323°K and a pressure of 49.0 · 107 N/m2.

  3. 3.

    The hexaborides of the rare-earth elements are characterized by high brittleness. Their bending strength at room temperature, is 125–183 MN/m2.
