In Situ Alloying of H13 Tool Steel With TiC via PBF‐LB/M

steel research international, EarlyView.
H13 tool steel is in situ alloyed with titanium carbides (TiC) in amounts up to 30 wt.%. This approach offers the advantage that the carbides melt only partially during processing, preventing excessive carbon enrichment of the steel matrix. The resulting microstructure consists of coarse, undissolved and fine, reprecipitated carbides, leading to grain ...

Microstructure, Defects, and Fatigue Response of High‐Strength Tool Steels

steel research international, EarlyView.
The martensitic tool steel family is designed for use in various working environments where they are subjected to repeatedly high mechanical loads. Despite the continuous upgrade of material´s microstructures through compositional development or processing techniques, defects remain a critical factor for the tool performance by leading to fatigue ...

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

steel 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,

Tailoring Microstructure and Hardness in Maraging 300 Steel via 2.4 wt.% Niobium Addition and Controlled Aging Treatments

steel research international, EarlyView.
High Nb (2.4 wt.%) addition to Maraging 300 steel drives lattice distortion and nanoscale Nb–Mo‐rich precipitation, confirmed by energy‐dispersive X‐ray spectroscopy mapping (Mo ~5.4 wt.%, Nb ~2.5 wt.%). Nanoindentation reveals strong matrix hardening (H >4.8 GPa) at 480°C aging, while 560°C induces ~1.92 vol.% reverted austenite, enabling tunable ...

Multi‐Scale Mechanical Behavior of Additive‐Manufactured 316L Stainless Steel Processed by Severe Plastic Deformation

steel research international, EarlyView.
The multi‐scale mechanical behavior of additive‐manufactured 316L stainless steel processed by directed energy deposition and high‐pressure torsion is explored. The influence of torsional strain on strength and microstructural evolution is revealed, indicating progressive grain refinement in the ultrafine regime, reaching strength levels nearing 1800 ...

Serviceability reserves of historic reinforced concrete slabs implications for structural reuse

Structural Concrete, EarlyView.
Abstract The transition to a circular economy in the construction sector requires reliable methods to assess whether existing reinforced concrete elements can be reused in new load‐bearing structures. A central question is whether slabs designed according to historical standards also meet today's serviceability requirements.
