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 ...

Crash Behavior of DP800–DP1000 Advanced High‐Strength Steel’s Dissimilar Resistance Spot Welded Joints Under Quasi‐static and High Strain Rates

steel research international, EarlyView.
The high‐strain‐rate behavior of resistance spot‐welded DP800–DP1000 joints is investigated. Results show that microstructural gradients across BM–HAZ–FZ govern hardness, strain rate sensitivity, and failure modes. While strength increases with strain rate, energy absorption is controlled by ductility, with DP800–DP800 joints showing superior ...

Tailored Hardening and Isothermal Bainitizing of Additively Manufactured Nitrogen‐Enhanced Martensitic Chromium Steel

steel research international, EarlyView.
Tailored heat treatments transform additively manufactured high‐nitrogen martensitic Cr steel from austenitic as‐built condition to high‐hardness states. Isothermal bainitizing at 250°C generates an ultrafine nanostructure and achieves higher hardness than conventional hardening and tempering, highlighting a promising postprocessing route for laser ...

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 ...

Anchorage performance of different punching shear reinforcement elements in cracked concrete

Structural Concrete, EarlyView.
Abstract Extensive research has been conducted on the bond and anchorage behavior of reinforcement elements in concrete. While many experimental studies have focused on uncracked concrete, the anchorage performance in the presence of cracks remains insufficiently understood.
