Influence of the microstructure on the degree of sensitization of a duplex stainless steel UNS S31803 aged at 650°C

De Melo E.B.; Magnabosco R.; De Moura Neto C. (2013)

This work evaluates the phase transformations during aging of an UNS S31803 DSS at 650°C and its influence on the DOS. The material was solution treated at 1175°C and then aged at 650°C for times up to 360 h. SEM-BSC images ...

Evaluation of microstructural effects on the degree of sensitization (DOS) of a UNS S31803 duplex stainless steel aged at 475°C

De Melo E.B.; Magnabosco R. (2015)

© 2015, NACE International.In this study, microstructural and electrochemical behavior of a UNS S31803 duplex stainless steel aged at 475°C were investigated. Hardness values increased with aging at 475°C and evidence of ...
