Minor Phase Evolution in Homogeneous T24 Welds
Popis výsledku v původním jazyce
This paper deals with the characterization of hardness, microstructure and precipitation processes in homogeneous T24 welds in the as-welded state and after laboratory PWHT at 745°C for 1 and 6 hours, respectively. Tempering of a T24 steel during qualityheat treatment is accompanied by intensive precipitation of MX, M7C3 and M23C6 particles in the bainitic matrix. It was found that SAW welding resulted in a pronounced dissolution of minor phases in the base material close to the joined faces. In the as-welded state microstructure of the CGHAZ was bainitic and the maximum HV10 value in this part of the HAZ reached 382 units. The dominant strengthening mechanism in the CGHAZ was attributed to transformation strengthening due to decomposition of austenite to bainite. Also the HV10 level in the bainitic filler metal (ca 320 HV10) was very close to the maximum acceptable hardness. PWHT at 745°C for 1 hour resulted in a significant decrease of hardness in the weld metal and especially in th
