Effect of welding consumables on shielded metal arc welded ultra high hard armour steel joints

Journal of the Mechanical Behavior of Materials, 2022
Materials with high hardness are usually preferred in armour applications and are difficult to weld due to high Carbon Equivalent (C.E). In this investigation, an attempt was made to weld Ultra-high Hard Armour (UHA) steel (having C.E of 0.91) by ...

Microstructural characterization of AISI 431 martensitic stainless steel laser-deposited coatings [PDF]

, 2011
High cooling rates during laser cladding of stainless steels may alter the microstructure and phase constitution of the claddings and consequently change their functional properties.

Microstructural and Corrosion Properties of Cold Rolled Laser Welded UNS S32750 Duplex Stainless Steel [PDF]

, 2018
The main goal of this work was to study the effect of plastic deformation on weldability of duplex stainless steel (DSS). It is well known that plastic deformation prior to thermal cycles can enhance secondary phase precipitation in DSS which can lead to

Effect of filler wires on mechanical properties of super-duplex stainless steel UNS S32750 and austenitic stainless steel 304 dissimilar joints welded with PCGTAW technique [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2022
This study addresses the effects of fillers (ERNiCrMo-3, ERNiCrMo-4 and ER309L) for joining 5 mm dissimilar metals of super-duplex steel (UNS S32750) and austenitic stainless steel (AISI 304) by using pulsed current gas tungsten arc welding.

Effects of aluminum on hydrogen solubility and diffusion in deformed Fe-Mn alloys [PDF]

, 2016
We discuss hydrogen diffusion and solubility in aluminum alloyed Fe-Mn alloys. The systems of interest are subjected to tetragonal and isotropic deformations. Based on ab initio modelling, we calculate solution energies, then employ Oriani's theory which

Corrosion Behavior in Different Media of Dissimilar Super Duplex Stainless Steel 2507 and Austenitic Stainless Steel 316 Welding by Using GTAW Process with Filler Type 316L

Journal of Techniques, 2023
The Super duplex stainless steel is the best of the stainless steel types because duplex stainless steel contains two phases, ferritic and austenitic, which promote this alloy's mechanical and corrosion properties compared to other types.

The hydrogen embrittlement sensitivity of duplex stainless steel with different phase fractions evaluated by in-situ mechanical testing [PDF]

, 2020
The influence of the austenite (gamma) phase fraction on the hydrogen embrittlement of duplex stainless steel is investigated. Heat treatments are performed to create two duplex stainless steel specimens, containing 50% and 44% of austenite, respectively.

Laser Additive Manufacturing of Duplex Stainless Steel via Powder Mixture

Journal of Manufacturing and Materials Processing, 2022
Laser additively manufactured duplex stainless steels contain mostly ferrite in the as-built parts due to rapid solidification of the printed layers. To achieve duplex microstructures (ferrite and austenite in roughly equal proportions) and, thus, a good
