| Popis: | The present work concerns the precipitation process of the sigma phase in the ferritic-austenitic stainless steel of duplex type SAF 2205. After the preliminary thermo-mechanical treatment, the steel was subjected to cold rolling up to 85% of reduction and subsequent annealing in the temperature range 650÷950°C for various times. Significant structural changes were observed in the course of annealing treatment affecting the formation of the ferrite and austenite texture. The development of annealing textures resulted from recovery and recrystallization processes in both component phases and the precipitation of the sigma phase. X-ray investigations included the phase analysis, measurements of pole figures for case of each phase, austenite and ferrite. Microstructure of analysis was conducted by means of optical microscopy. The microstructure and texture of duplex type steel after annealing result from the precipitation process of sigma phase, depend on the temperatures and time of annealing. |
