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

steel 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.

Alloying Strategies for Secondary Hardening in High‐Boron Cold Work Tool Steels: A Comparative Study

steel research international, EarlyView.
The influence of tungsten, vanadium, manganese, and silicon on the microstructure and tempering behavior of high boron tool steels is investigated. It is shown that tungsten contributes very little, whereas vanadium leads to tempering carbides, detected by atom probe tomography . Manganese and silicon enable solid solution strengthening.

Increasing the Reuse Potential of High‐Strength Steels by Extending the Fatigue Life through Surface Treatments

steel research international, EarlyView.
Surface reconditioning through mechanical and electrochemical polishing is shown to extend the fatigue life of predamaged 42CrMo4 steel by over 12 times. By removing ≈100 μm of surface material, surface‐driven fatigue damage is mitigated. This study introduces a reuse potential metric to evaluate fatigue recovery and support sustainable steel reuse.

Influence of Competitive C–P Segregation on Austenite Grain Growth in Iron Alloys

steel research international, EarlyView.
This study investigates how carbon influences phosphorus‐induced solute drag effects during isothermal annealing of austenite grain growth in Fe–C–P alloys. Using in situ high‐temperature laser scanning confocal microscopy and density functional theory simulations, it demonstrates that carbon above a critical temperature significantly reduces P ...
