Thermomechanical Treatment of Duplex SAF 2507 Steel

Popis výsledku v původním jazyce

This contribution deals with thermomechanical treatment of SAF 2507 duplex steel. The purpose of the treatment was to achieve the desired shape and hardness of the workpiece. It was intended to use a hardness contribution from precipitates of intermetallic phases. Since intermetallic precipitation is very sensitive to the forging temperature and post-forging cooling rate, the entire forging process and post-forging treatment route was first simulated using numerical modelling. Above all, the rate of cooling after forging was monitored at several pre-defined points because it has a major effect on the resulting microstructure and mechanical properties in duplex steel. The presence of intermetallic phases was detected using optical and scanning electron microscopy. Their types were identified by means of EBSD analysis. As intermetallic precipitation causes severe embrittlement, notch impact toughness was measured upon individual experiments.
