Welding power and post‐weld heat treatment (PWHT) at 850°C influence phase transformations in S32205 duplex stainless steel, promoting sigma phase formation and reducing corrosion resistance. PWHT at 850°C also replicates HAZ‐like microstructures in base metal, enabling improved characterization of weld joint properties.

Mitochondrial function predicts dominance status in brown trout
Read the free Plain Language Summary for this article on the Journal blog. Abstract In social hierarchies, winning contests confers better access to food, shelter and reproductive opportunities. Clear dominance relationships are often apparent even when opponents are matched for experience, age, size and other obvious characteristics.

Hydrogen cracking in duplex stainless steel weldment.
The restraint weld cracking test was conducted to investigate the hydrogen cracking in duplex stainless steels which contain various ferrite/austenite ratio. The gas tungsten arc (GTA) welding was applied with the argon shielding gas containing 10% hydrogen. The effects of preheating or post weld heat treatment (PWHT) on the hydrogen cracking were also

Molecular dynamics simulations were utilized to explore the influence of grain boundary hydrogen concentration on the hydrogen embrittlement sensitivity of polycrystalline iron. This graphical abstract visualizes the corresponding microstructural evolutions, with results demonstrating that elevated hydrogen concentration reduces the yield and ultimate ...

Hydrogen embrittlement in super duplex stainless steels
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 ...

A Conceptual Framework and Methods for Studying the Connectivity of Fishes
ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...
