Description
Summary:This item has been previously abstracted from original Russian. Interaction has been studied in vacuum and temperature range 800-1700 deg C in the process of production of B sub 4 C-ScB sub 2 composite by mass-spectrometric method and chemical and x-ray diffraction analysis. It is shown that during the oxide reduction at first metallic scandium is formed and then its boride. In this case B sub 4 C is solved in the lattice to 0.2 wt.% Sc, which increases microhardness of the B sub 4 C-base phase as compared with pure carbide 1.5 times.
