Sigma Phase Detection in Duplex Stainless Steel Based on Correlation to Current and Potential in Micro Electrode Electrochemical of Surface
Duplex stainless steels are widely used due to their good mechanical properties and corrosion resistance.However, they are susceptible to microstructural fragility related to harmful transformations taking place in intermetallic phases, such as the sigma phase.These transformations reduce mechanical properties like toughness and corrosion resistanc
