Various radiotracers were used to investigate the dissolution of alloying additions and their distribution in steel. The alloying specimens FeCr, FeMn, SiMn and FeTi that had locally been labelled were simultaneously added to the steel melt. Sampling was carried out by means of a special probe. The distribution of the elements in steel teas determined by gamma-spectrometric evaluation of the samples using a multichannel analyzer type TRACOR TN 4500.
