Methods for solubility determination and deoxidizing conditions of specimens have been examined and comparison of experimental results with thermodynamic calculations shows that insufficient deoxidation of melts may lead to inaccurate results.Experimental results obtained with helium argon and molybdum methods are compared, and the helium method appears to be the most reliable. In the present investigation, all determinations except the hydrogen solubility in nickel were made with the helium method.Addition of copper to molten iron increases the solubility of hydrogen up to 25％ Cu, the solubility appears to decrease with further addition. The addition of nickel to liquid Fe-Cu alloys up to 7％ Ni has no appteciable effect on the solubility of hydrogen. 收稿日期: 1964-01-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 杨维琛 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1964/V7/I1/1 [1] Sieverts, A.: Z.
