Sigma Phase Detection in Duplex Stainless Steel Based on Correlation to Current and Potential in Micro Electrode Electrochemical of Surface [PDF]

Materials Research
Duplex stainless steels are widely used due to their good mechanical properties and corrosion resistance. However, they are susceptible to microstructural fragility related to harmful transformations taking place in intermetallic phases, such as the ...

Out‐of‐plane stability design of stainless steel beams by GMNIA with strain limits

ce/papers, Volume 9, Issue 2-3, Page 2050-2054, September 2026.
Abstract Design by geometrically and materially nonlinear analysis with imperfections (GMNIA) using beam finite elements and strain limits has emerged as an accurate and efficient design approach, capturing the key structural behaviour while reducing the need for separate cross‐section classification and member design checks.

The effect of alloying method on the structure and properties of sintered stainless steel

Archives of Metallurgy and Materials, 2017
Sintered duplex stainless steels (SDSSs) appear to be very interesting and promising materials that can be used in many industrial sectors. Ferrite improves material strength while austenite increases hardness and corrosion resistance.

Effect of niobium in the phase transformation and corrosion resistance of one austenitic-ferritic stainless steel [PDF]

Materials Research, 2014
Austenitic-ferritic stainless steels containing 0.2% and 0.5% niobium were evaluated with respect to the microstructures, microhardness, pitting potential resistance, electrochemical impedance and wearing tests. Niobium is an alphagenic element and has a

Optimization of Material Density and Strength in Super Duplex 2507 Stainless Steel via Selective Laser Melting: CCD‐PSO‐DFA Approach

Engineering Reports, Volume 8, Issue 9, September 2026.
Systematic framework has been established to model, analyze, and optimize the properties of SLM parts. The major results drawn from the proposed work: CCD‐based modeling for density and UTS of SLM‐fabricated SDSS 2507. Scan speed showed the highest influence on density and tensile strength.

Experimental and Comparative Study of the Corrosion Behavior of Lean Duplex Stainless Steel in Seawater

Materials and Corrosion, Volume 77, Issue 9, Page 1399-1423, September 2026.
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.

Influence of Strain Rate on the Strain Hardening Behavior of a Lean Duplex Stainless Steel

MetalMat, Volume 3, Issue 3, September 2026.
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.

Hydrogen cracking in duplex stainless steel weldment.

QUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY, 1990
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
