A study of the macroscopic distribution of oxygen in a steel rod by neutron-activation and vacuum fusion techniques
The distribution of oxygen was determined along the length of a steel rod. Neutron-activation and vacuum fusion techniques were used alternatively, and the relevant pieces of apparatus and methods are described. The over-all average oxygen content determined by neutron-activation analysis was 129 p.p.m., in excellent agreement with 128 p.p.m. found by vacuum fusion. The results further show the continuity between the two sets of results, and also a definite inhomogeneity in the macroscopic distribution of oxygen.
