%X Traces of born in the range 0,002-0,009 % are usually added to many grades of steel. The effect of boron on phase transformations and hardenability of low carbon low alloy steels depends on the form of its behavior in solid solution either in segregations or in precipitations. Temperature and cooling rate determine the existence of boron segregations on grain boundaries. In present paper simulations of boron concentrations were calculated with computer programme DICTRA for low carbon 0,08 %C steel with 0,006 % boron. Investigations were carried out for temperature 1300 ¨C 700¡ãC and cooling rates from 1¡ãC/s to 100¡ãC/s. The changes of boron concentrations in austenite and ferrite after commencement of ¦Ã¡ú¦Á phase transformation were established.
