Materials and Corrosion, EarlyView.The localized corrosion behavior of lean duplex stainless steel EN 1.4062 is systematically compared with austenitic and higher‐alloyed duplex grades in natural seawater. A clear resistance ranking is established, highlighting EN 1.4062 as a cost‐effective alternative for limited marine exposure.

Analysis of Corrosion and Wall Perforation in the Heat Exchanger Made of AISI 316L Stainless Steel
Materials and Corrosion, EarlyView.Elevated passivation temperature is identified as the dominant factor triggering localized corrosion and subsequent perforation of AISI 316L heat exchanger tubes. Electrochemical and complementary characterization results show that the alloy retains high resistance to general, pitting, and intergranular corrosion, indicating that failure primarily ...

Hydrogen embrittlement in super duplex stainless steels [PDF]
Materialia, 2019 In super duplex stainless steels (SDSSs), both austenite and ferrite are susceptible to hydrogen embrittlement, however there is a lack of understanding into the effect of hydrogen in each phase. In this study, in neutron diffraction was applied on hydrogen-charged (H-charged) samples to investigate the hydrogen embrittlement behaviour in super duplex ...

Materials and Corrosion, EarlyView.Hydrogen‐enhanced SCC of WAAM Inconel 625 in 3.5 wt.% NaCl solution. Hydrogen charging reduces passive film stability (lower corrosion potential) and promotes pitting at Laves phase/matrix interfaces. Stress corrosion cracks propagate along Laves‐rich regions, leading to quasi‐cleavage brittle fracture.

Influence of Strain Rate on the Strain Hardening Behavior of a Lean Duplex Stainless Steel
MetalMat, EarlyView.The aim of this study was to examine how strain rate influences the compressive strain‐hardening behavior of a lean duplex stainless steel LDX 2101. Microstructural analysis using electron backscatter diffraction (EBSD) revealed a strain‐induced austenite‐to‐martensite transformation.
