Verfahren zur Herstellung von Metallen und Legierungen in reproduzierbarer Qualitaet

摘要

A metallurgical process is controlled by directly measuring the oxygen content of a specimen taken from the melted charge. The specimen is subjected to neutron radiation, and the radiation of the resulting 16N isotopes is measured. Addition agents are then used to alter the oxygen content of the charge to a desired value. Preferably, the specimen is bombarded simultaneously with a specimen of known oxygen content, and the differences in radiation of the known and unknown specimens are automatically displayed and/or used to effect the desired additions.
