Sažetak
Heat treatment is optimally carried out in two modes: normalization or quenching at 900 °C and subsequent tempering at 650 °C. With this heat treatment, there are two temperature maxima for the release of aluminum nitrides in austenite (900 °C) and ferrite (650 °C). Aluminum nitrides with a cubic lattice released from ferrite are more dispersed and have a better effect on the properties of steel than hexagonal AlN formed from austenite. For the complete binding of nitrogen to AlN nitrides, the amount of aluminum in carbon steel must be ≥40 • 10-3 wt. %. To obtain fi ne nitrides and maintain a suffi ciently high fluidity of carbon steel, the optimal aluminum content should be (40 - 60) • 10-3 wt. %.
