Terminology Relating to Nonmetallic Elements in Metals

AT the symposium on gases in metals held at the Annual Meeting of the Institute in New York in February, 1933, a suggestion was made1 that the term "gases in metals" as now employed is unsuitable as descriptive of the substances usually involved in that term. The Executive Committee of the Iron and Steel Division thereupon appointed a subcommittee, composed of the authors of this paper, to study the "nomenclature involved in the general subject of gases in metals, including the name itself" and to report its findings to the Executive Committee. The subcommittee decided at once to discuss the subject with an "Advisory Council" composed of representative metallurgists, metallographers and analytical and physical chemists in the Pittsburgh district.2 As a result of conferences held by the subcommittee and with the Council, a report with recommendations was submitted to the Executive Committee at an open meeting on Oct. 5, 1933, during the National Metals Congress in Detroit. The report and recommendations were accepted, and the subcommittee was instructed to proceed with the dissemination of the report for the purpose of having its recommendation generally adopted either as it was or in a modified form as a result of further discussion.
