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

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.

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.

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
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.

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. To

Fracture of drilling head pipe connection due to quenching of heat affected zone (HAZ)
The drilling head pipe connection is made of quenched and tempered steel 34CrNiMo6. The steel characteristic is high hardenability. Due to unsuitable and untested welding technology the heat affected zone (HAZ) cooling rate after welding surpassed the ...

This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed
