A Comparative Study of Directed Energy Deposition‐Arc and Casting: Enhancing Mechanical and Thermal Properties of Hot‐Work Tool Steels

open access: yessteel research international, EarlyView.
The study investigates the influence of DED‐Arc/M versus casting on the microstructure and material properties of X40CrMoV5‐1 (AISI H13) hot‐work tool steel. DED‐Arc/M yields finer microstructures, superior mechanical strength, and ductility, but slightly reduced thermal conductivity.

Investigating the Iron‐Steam Process for Coupling With SOEC and SOFC: A Step Toward Integrated Hydrogen and Electricity Storage

open access: yessteel research international, EarlyView.
Fixed‐bed reactor experiments (10 L) validate the iron–steam redox process, bridging material‐scale research and industrial power‐to‐power applications. Coupled with SOEC/SOFC systems, this framework defines critical interfaces for heat and gas management. Results confirm reproducible hydrogen storage and release, demonstrating technical feasibility at

Exploiting Residual Elements Arising from Scrap Steel in Future Sustainable Steel Alloy Design

open access: yessteel research international, EarlyView.
Herein, the effects of residual elements Cu and Sn on grain growth, recrystallization, and phase transformation in C–Mn steel are summarized, and a case study is presented on how the presence of residual elements can be exploited to reduce deliberate Nb microalloying while achieving the same grain size control and strength during thermomechanical ...

Influence of Heat Treatment Temperature on Crevice and Pitting Corrosion of UNS S32205 Duplex Stainless Steel

open access: yessteel research international, EarlyView.
Heat treatments that alter the proportions of austenite and ferrite phases or induce the precipitation of phases such as sigma in duplex stainless steel UNS S32205 make it more susceptible to pitting and crevice corrosion. However, the effects of these treatments are not always evident when analyzed using the cyclic polarization technique.

Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

open access: yessteel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

Effect of Postweld Heat Treatment on Laser‐Welded Duplex Stainless Steel: Crystallographic Patterns and Fatigue Behavior

open access: yessteel research international, EarlyView.
Laser welding of duplex stainless steel disrupts phase balance, promotes nitride precipitation, and reduces fatigue resistance. Postweld heat treatment restores austenite and dissolves nitrides, but the resulting crystallography and phase morphology still impair fatigue performance.

Microstructure Characterization of Bending Effects in 304L Stainless Steel Cladded with Low‐Alloy Steel Weld

open access: yessteel research international, EarlyView.
Prebending of 304L/Q345R cladded plates significantly alters the subsequent weld thermal cycle and modifies the local interfacial microstructure. Combined electron backscatter diffraction (EBSD) and microscopy analysis demonstrates that deformation twinning, martensitic transformation, and defect initiation are concentrated at the trimaterial junction,

Effect of Double Annealing on the Microstructure and Mechanical Properties of a Medium Manganese Steel

open access: yessteel research international, EarlyView.
A double intercritical annealing strategy is proposed to tailor the multiphase microstructure and mechanical response of a medium‐Mn steel. The treatment produces an ultrafine mixture of ferrite, martensite and multiple austenite populations with graded thermal and mechanical stability, formed through austenite reversion and controlled retransformation.
