Electrochemical characterization of sigma phase in superduplex stainless steels: LSV-KOH as a promising methodology over DL-EPR

This work analyzed the volume fraction of the sigma phase in a superduplex stainless steel UNS S32760. Two electrochemical testing methodologies were applied for this purpose. Firstly the DL-EPR test was performed in three different electrolytic solutions. The LSV-KOH test was also used, a recent me...
