摘要：
The results of determining the phase composition for steels, in particular the amount of ferritic phase, given by G.G. Kolchin, et. al., do not correspond to their chemical composition. We have also established that nitride-forming elements (Al and V) are found completely in solid solution and do not take part in formation of nitrides or carbonitrides. The content of nitrogen obtained by Kolchin, et. al. for steel 3 is higher than the solubility for nitrogen in it. There are numerous data in the literature that introduction of nitrogen into austenitic-ferritic steels (about 30% ferrite) promotes an increase in strength characteristic with a simultaneous reduction in the amount of ferritic component to several per cent.
