Abstract

Quaternary borocarbide system YRh₃B_xC_1-x phase have been synthesized by arc melting method and studied for their microhardness and oxidation resistance. Perovskite-type YRh₃B and YRh₃C form a continuous solid-solution in the range of 0≦x≦1 with a cubic structure (space group: Pm3m, Z=1). The microhardness of YRh₃B_xC_1-x increases with increasing boron content. Thermogravimetric analysis indicates that the oxidation onset temperature also increases with boron content. Thus, it is indicated that the chemical stability of the perovskite-type borocarbide solid-solution YRh₃B_xC_1-x is strongly dependent on the boron content.
