Fatigue Behavior and Crack Propagation of Powder Metallurgical High‐Boron Tool Steels

steel research international, EarlyView.
High‐boron tool steels are produced by powder metallurgy and ingot casting with subsequent swaging. The hard phase‐rich microstructures are investigated and characterized. The fatigue behavior is tested in a 3‐point bending setup and compared to a conventional cold work tool steel.

Additive Manufacturing of Hot‐Work Tool Steel by In Situ Alloying Using Laser Powder Bed Fusion and Directed Energy Deposition—Strategies to Improve Chemical Homogeneity

steel research international, EarlyView.
To support future alloy development a powder mixture is processed by laser additive manufacturing. The powder mixture containing Mo‐ and W‐rich tracers is processed by powder bed fusion using single and double laser exposure and by directed energy deposition which provides drastically enlarged melt pools.

Influence of Cooling Rates and Titanium Content on Hot Ductility in Niobium‐Fixed Microalloyed Steels

steel research international, EarlyView.
The hot ductility of four microalloyed steels was examined under varying cooling rates and titanium contents. Hot tensile testing and microscopic analysis revealed that ferrite formation and TiNb(CN) precipitation critically influence hot ductility. Lower cooling rates enhance ductility by increasing ferrite thickness and modifying precipitate features,

Recycling End‐of‐Life Solid Oxide Cell Interconnect Assemblies into Commercial‐Grade AISI 304 Stainless Steels

steel research international, EarlyView.
This study validates a recycling pathway for converting interconnect assemblies from end‐of‐life SOC stacks into commercial‐grade AISI 304 steels. Using scrap‐based steelmaking operations, austenitic cast steels with <4.0% δ‐ferrite are successfully produced.

Thermodynamic Modeling of Sn–C and Fe–Sn–C Systems for the Tramp Elements Control in Steel Production

steel research international, EarlyView.
A CALculation of PHAse Diagrams thermodynamic modeling for Fe–Sn–C system is carried out. The model and the developed database can be used to calculate phase diagrams and thermodynamic properties of this system over wide temperature/composition range, and a part of a larger thermodynamic database for steel and alloy system, and effectively used to ...
