合成了四元硼碳化物YRh_3B_xC_（1-x）系固溶体，并从显微硬度和抗氧化性的角度对其进行了研究。钙钛矿型YRh 3B和YRh 3C形成具有立方结构（空间群：Pm 3 m，Z=1）的在0 π x π 1范围内的连续固溶体。YRh_3B_xC_（1-x）合金的显微硬度随硼含量的增加而增加。氧化起始温度也随着硼含量的增加而增加。因此，这表明，固溶体YRh_3B_xC_（1-x）的化学稳定性强烈依赖于硼含量。
Solid solutions of the quaternary borocarbide system YRh3BxC1-x have been synthesized and studied from the viewpoints of 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 YRh3BxC1-x increases with increasing boron content. The oxidation onset temperature also increases with boron content. Thus, it is indicated that the chemical stability of solid-solution YRh3BxC1-x is strongly dependent on the boron content.
