Hydrogen induced stress cracking behavior in duplex stainless steels

摘要

Duplex stainless steel (DSS) that has a heterogeneous microstructure of austenite and ferrite suffers from hydrogen induced stress cracking,HISC,in subsea applications.In this study,theHISC behaviors in three super duplex stainless steels with different microstructures have beeninvestigated by a simulated HISC test,combined with SEM and EBSD analysis.
