HWTS 50 Tool Steel Tailored for Laser Powder Bed Fusion: Sliding Wear of Bare Surfaces and Nitriding Response in Comparison with 18Ni300 and AISI H13

steel research international, EarlyView.
This work investigates the wear resistance and nitriding behavior of PBF‐LB/M‐processed Osprey HWTS 50, a lean hot work tool steel. Three heat treatment conditions are compared to conventional wrought H13, H11, and PBF‐LB/M 18Ni300. The study highlights HWTS 50's enhanced nitrogen diffusion, deeper nitriding hardness depth, and comparable or improved ...

Phase Transformation Behavior of Continuously Cooled Fe–C–V–(Mo) Alloys

steel research international, EarlyView.
Additions of vanadium and molybdenum microalloying are shown to reshape phase transformations in clean low‐carbon steels. By tracking microstructural shifts during continuous cooling, the work uncovers the correlation between transformation kinetics, ferrite morphology, and hardness.

Reducing the use of Fossil Carbon and Fuels to Defossilize the Electric Steelmaking Route: Evaluation of the Effects of Alternative C‐Bearing Materials and Hydrogen in the Electric Arc Furnace

steel research international, EarlyView.
The experiments and simulations demonstrate that, in general, alternative carbon sources can decrease fossil CO2 without adversely impacting EAF process and product. High plastics and tires ratios cause unsafe conditions and poor slag foaming. Hydrogen in EAF burners decreases CO2 but increases water vapor, which can raise the hydrogen content in ...

Numerically efficient mechanical modeling of reinforced concrete membrane elements with fixed, interlocked cracks

Structural Concrete, EarlyView.
Abstract Compression field approaches such as the Cracked Membrane Model with fixed, interlocked cracks (CMM‐F) are efficient tools for the mechanical modeling of reinforced concrete elements, providing the mechanical model σ=fε$$ \boldsymbol{\upsigma} =f\left(\boldsymbol{\upvarepsilon} \right) $$ required for finite element analyses.

Pre‐failure behavior of continuous post‐tensioned and post‐grouted beam in case of tendon failure

Structural Concrete, EarlyView.
Abstract Grouted tendons are a common solution for long‐span bridge structures. The grout provides bond and corrosion protection for prestressing steel. However, if the grouting is defective, corrosion of the prestressing steel may initiate and eventually lead to tendon failure.
