| Research Abstract |
A novel method has been established for the determination of the solubility limits of metallic solid solusion phase. The proposed method includes the sputtering of C and/or B on to the well-polished specimen, followed by aquision of inward concentration profiles from the suface by glow discharge optical emission spectroscopy. A feasibility check was done on a well-established alloy system of the Ni-C binary, and the present method was confimed to be effective, since the obtained data agreed with the data in literature. Based on this knowledge, the solubility limit of C in Pt, which had been unknown so far, was determined in this study.
