Computer Modeling of the Ferrite‐To‐Austenite Transformation in a Super‐Duplex Stainless Steel and the Important Role of Trans‐Interface Diffusion

steel research international, EarlyView.
An accurate moving boundary model for volume diffusion containing boundary conditions from trans‐interface diffusion (TID) simulates the austenite growth during cooling. TID of Cr, Mo, N and Ni enhance growth kinetics. Without TID, compositions of the interface region change, decreasing the driving force for growth and finally causing numerical ...

Study on Microbiologically Influenced Corrosion Resistance of Stainless Steels With Weld Seams

Frontiers in Materials, 2020
Stainless steels are widely used in various industries due to their desirable combination of mechanical properties and corrosion resistance. However, corrosion of stainless steels was reported seriously on the weld seam areas, and it is not exceptive for

Influence of Surface Roughness and Temperature on Niobium Cathodic Cage Duplex Treatment Applied to VP20TS Steel

steel research international, EarlyView.
Niobium cathodic cage duplex treatment is applied to VP20TS steel to evaluate the influence of surface roughness and temperature on coating performance. Results show that higher temperatures promote thicker nitride layers and increased microhardness, while finer surface preparation enhances adhesion and wear resistance, revealing optimal conditions for

Investigation of Serrated Flow in Intercritically Annealed Medium Manganese Steel by In Situ Synchrotron X‐Ray Diffraction

steel research international, EarlyView.
Serrations and stepwise austenite phase transformation were observed in cold‐rolled and annealed medium manganese steels. By in situ XRD experiments, these two phenomena were studied simultaneously. The results show that DSA leads to the creation of PLC bands and load drops in the specimen.

EXPERIMENTAL INVESTIGATIONS OF NITROGEN ALLOYED DUPLEX STAINLESS STEEL IN DRY MILLING PROCESS [PDF]

Journal of Engineering Science and Technology, 2018
Duplex stainless steels are generally more difficult to cut because of their high toughness, low heat conductivity, more strain hardening rate and more built-up edge formation.

Moment‐curvature behavior of continuous reinforced concrete slab strips—Experimental determination and modeling

Structural Concrete, EarlyView.
Abstract With the market introduction of new reinforcing materials, such as corrosion‐resistant steel, the effect of their stress–strain relationship on the ductility of reinforced concrete structures needs to be evaluated. Their moment‐curvature behavior significantly influences bending moment redistributions, rotation capacity, and deformation at ...

Application of Duplex Stainless Steels in Manufacture of Equipment for Nuclear Power Station

Teshugang, 2012
The austenite-ferrite duplex stainless steels have stable austenite phase and ferrite phase structure that have higher mechanical properties and excellent pitting, intergranular corrosion and stress corrosion resistance, therefore the steels are wide ...

On the pitting resistance of friction stir welded UNS S82441 lean duplex stainless steel

Journal of Materials Research and Technology, 2019
Friction stir welding has been considered as an alternative to fusion welding processes of stainless steels. A lean duplex stainless steel, grade UNS S82441, has been recently developed and is prone to localized corrosion, such as pitting when exposed to

Exploring the potential of Textile Reinforced Concrete for corrosion‐insensitive retaining walls

Structural Concrete, EarlyView.
Abstract In a context where durability concerns, particularly the corrosion of steel reinforcement, remain a critical challenge for conventional reinforced concrete structures under severe exposure, Textile Reinforced Concrete (TRC) is emerging as a promising alternative.

Electrochemical Hydrogen Charging of Duplex Stainless Steel [PDF]

Corrosion, 2018
This study evaluates the electrochemical hydrogen charging behavior and interaction between hydrogen and the microstructure of a duplex stainless steel. A saturation level of approximately 650 wppm is reached after 10 d of charging. The data are compared with a model resulting in a diffusion coefficient of 2.1 × 10−14 m2/s.
