Effect of 475°C embrittlement on the low cycle fatigue behaviour of lean duplex stainless steels

Abstract: Lean duplex stainless steels (LDSSs) with lower nickel and molybdenum are less susceptible to suffer spinodal decomposition than standard duplex stainless steels. It is the purpose of this work to study the effect of thermal embrittlement on the low cycle fatigue behaviour of 2 LDSSs with different Creq and Nieq. The correlation between the fatigue behaviour and the dislocation structure is attempted. Transmission electron microscopy was used to observe the dislocation microstructure. Additionally, STEM‐EDS te… Show more

“…As a consequence of the TEM analysis performed on the 475°C tempered DSS and SSS, it is possible to point out that after 1000 hours: ‐spinodal decomposition is only scarcely developed and is not clearly evident for all the investigated stainless steel; ‐G phase precipitation is more and more developed with the content increase of G phase forming elements (mainly Ni, Mo). …”
