Effect of Nitrogen‐Added Shielding Gas on Microstructure Evolution of Welded Joints by Gas Tungsten Arc Welding Process in Duplex Stainless Steel 2205

steel research international, Volume 95, Issue 5, May 2024.
A challenge in welding duplex stainless steels is to limit ferritization in the heat‐affected zone to ensure high corrosion resistance. The work describes the influence of nitrogen gas in the Ar–N2 shielding atmosphere during a gas tungsten arc welding process.

Review on Fatigue of Additive Manufactured Metallic Alloys: Microstructure, Performance, Enhancement, and Assessment Methods

Advanced Materials, Volume 36, Issue 17, April 25, 2024.
Additive manufactured metals have excellent mechanical properties, but their fatigue resistance is an exception. This article reviews the processes attributes, hierarchical microstructure, fatigue performance, and evaluation methods. The fatigue failure mechanisms of printed metals were summarized, and the competition between trans‐scale ...

Influence of surface treatment on metal dusting resistance of welds

Materials and Corrosion, Volume 75, Issue 3, Page 371-385, March 2024.
Fe contaminations enhanced metal dusting pit formation on brushed welds of Ni‐based alloys. The best performance of the welds was achieved by grinding, this is attributed to the deformation of the sub‐surface zone. Additional protection by on‐site slurry aluminization was successfully demonstrated.
