INVESTIGATION OF THE EFFECT OF THERMOMECHANICAL PROCESSING ON MICROSTRUCTURE AND CORROSION RESISTANCE OF 321 AUSTENITIC STAINLESS STEEL

In this study, microstructural changes in the thermomechanical processing and its effect on the corrosion behavior of 321 austenitic stainless steel were investigated. EDS analysis and optical microscopy were used to identify precipitates and microstructure, respectively. To evaluate the corrosion p...
