Sažetak
After welding, heat treatment of weld joints on components made of high-temperature steels is usually necessary. In this work, several microstructures occurring in the heat affected zone (HAZ) in X10CrMoVNb9-1 hightemperature steel were simulated: Coarse grained HAZ (CGHAZ), two different fine grained HAZ (FGHAZ) and intercritical HAZ (ICHAZ). Test pieces were mechanically tested at room temperature in as welded condition and after post weld heat treatments at 760 °C and 780 °C. At both temperatures, already after 0.5 h even the hardness of CGHAZ met the requirements of EN ISO 15614-1, and also the impact toughness was significantly above the required minimum. However, to decrease the hardness of all HAZ subzones close to 250 HV, which is within the hardness range of as delivered normalized and tempered material, it took 4 h at 280 °C and 8 h at 760 °C.
