Abstract

Language:

The effects of the cooling rate on the solidification and microstructure evolution in the duplex stainless steel SAF 2205 were studied using differential scanning calorimetry (DSC) and light microscopy. A ferritoscope was employed to measure the ferrite content. The findings revealed that the cooling rate significantly influences the δ-ferrite nucleation temperature and the width of the solidification interval. As the cooling rate increased, the amount of δ-ferrite increased, while the presence of austenite in the ferrite matrix decreased and its morphology transitioned to an acicular form. The implementation of a two-cycle DSC experiment facilitated a more precise interpretation of the collected data. These results enhance the understanding of solidification behavior in duplex stainless steels and provide insights into optimizing processing conditions to tailor their microstructural characteristics for improved performance in various applications.
