Sažetak
The result on investigation of fine grained structural steel microstructure at hot rolling conditions is given. Billets of 55 mm thickness were heated to 1200 °C and rolled starting at this initial temperature to obtain a rolling temperature interval from 1050 °C to 760 °C. From the rolled plates of 16 mm thickness specimens for optical microscopy werw prepared by conventional way. The portions of precipitates of aluminium (AlN) and niobium carbide (NbC) werw determined using a modified halogen extraction method. The results of the investigation indicated that no grain size decrease could not be expected if the rolling plates are performed significantly below the austenite to feritte transformation temperature.
