Optimization of spark plasma sintering temperature: Influence on microstructure and mechanical properties of SAF 2507 duplex stainless steel

Original language description

Duplex stainless steels offer a wide range of application due to good mechanical properties and high corrosion resistance. Only duplex stainless steel with microstructure consisting of equal ferrite and austenite contents meets this requirement and other secondary phases deteriorate the properties. Microstructural and uniaxial tensile properties of the SAF 2507 duplex stainless steel (SDSS) prepared via spark plasma sintering are reported in this work. The SAF 2507 SDSS powder was consolidated via spark plasma sintering at 900 degrees C and 1100 degrees C. The microstructure of the samples sintered at the temperature of 900 degrees C contained numerous pores (volume porosity of 16 %), significant fraction of the sigma-phase and the strength and plastic properties of this sample are low. The good mechanical properties. Post-manufacturing solution annealing resulted in a uniform austenite-ferrite microstructure for both spark plasma sintering temperatures. In the case of the sample sintered at 1100 degrees C, only minor changes occurred in microstructure , mechanical properties during post-manufacturing heat treatment. Properties of spark plasma sintered material were compared with the same alloy prepared by additive
