Abstract
The inert gas fusion method has been improved and evaluated for use as a rapid method of determining oxygen in steel samples. The method has been tested by comparison with the vacuum fusion method on a variety of steels. It permits a determination of oxygen in most steels in 7 minutes or less. Most of the advantages of vacuum fusion are retained in the method, yet a considerable simplification in apparatus and its operation is gained. The analyses are in agreement with those obtained by vacuum fusion. (auth)
