Effect of sintering temperature on the mechanical and electrochemical properties of austenitic stainless steel

The present study compares the densification response and the mechanical and electrochemical behavior of austenitic (AISI 316L) stainless steel conventionally sintered in solid state (1200 and 1300 °C) and supersolidus (1400 °C) state. The densification increased with temperature and the overall performance of austenitic stainless steel (AISI 316L) was significantly improved with supersolidus (1400 °C) state sintering. A detailed correlation has been drawn between the processing parameters, the evolved microstructure and the resulting properties.
