Near‐Atomic Investigation on the Elemental Redistribution During Coprecipitation of Nano‐Sized Kappa‐Type and B2 Precipitates in an Al‐Alloyed Lightweight Steel

steel research international, EarlyView.
Elemental redistribution during coprecipitation of kappa (κ)‐type and B2 precipitates in an Al‐alloyed lightweight steel is revealed by atom probe tomography (APT) and density functional theory (DFT). Fe and Ni redistribution promotes the evolution of B2 phase from NiAl‐type toward FeAl‐type and improves the stability of κ and B2 phases during ...

Helium bubble characterization in tritium aged austenitic stainless steels

Nuclear Materials and Energy
Tritium, as an isotope of hydrogen, permeates throughout most known materials and decays over time into 3 He causing both hydrogen and helium embrittlement.

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 ...

Multifaceted Behavior and Versatility Features of Ferritic Stainless Steels, Part II: Investigating Electromagnetic, Mechanical, and Corrosion Behavior

steel research international, EarlyView.
This review's second part details the mechanical, corrosion, and electromagnetic behaviors of FSSs. It integrates the foundational microstructure (texture/defects/precipitates) and processing effects from Part I to establish and analyze complex property–property interrelationships critical for high‐performance applications.

Atomic‐Scale Insights Into Tramp Element Segregation and Mechanical Performance of a Low‐Carbon Steel

steel research international, EarlyView.
Despite increased hardness, elevated tramp element concentrations in a ferritic‐pearlitic low‐carbon steel lead to enhanced toughness accompanied by a more homogeneous and finer ferritic microstructure. Atom probe tomography reveals pronounced segregation of some tramp elements at grain boundaries and ferrite–cementite interfaces, together with ...

Effects of autoclave sterilization on the dimensional stability of implant surgical guides: A 3D in vitro analysis

Journal of Prosthodontics, EarlyView.
Abstract Purpose Surgical guides are medical devices used in static implant surgery to replicate the prosthetic and surgical implant position planned with computer‐assisted software before surgery. Their use reduces invasiveness and improves safety and outcomes of implant surgery, provided that their accuracy is ensured from design to manufacturing and

Assessment of the Influence of Specimen Size on the Performance of CLF-1 Steel Based on the GTN Model

Metals
Irradiation embrittlement occurs in the cladding materials of fusion reactors during irradiation. Determining the ductile–brittle transition temperature via Charpy impact testing is the primary method for evaluating irradiation embrittlement.
