Strain‐Induced NbC Precipitation as a Governing Mechanism for Hot Deformation Resistance in CrNiMnMoB Ultrahigh‐Strength Steels

open access: yessteel research international, EarlyView.
Strain‐induced NbC precipitation governs hot‐deformation resistance in CrNiMnMoB ultrahigh‐strength steel by suppressing dynamic recrystallization, increasing activation energy, and refining martensitic substructures. The precipitation response is controlled by temperature, supersaturation, and strain rate, with slow deformation promoting extensive NbC

A novel integrated circular radiography (ICRAD) phantom for evaluating non‐uniform image quality metrics in radiography

open access: yesMedical Physics, Volume 53, Issue 10, October 2026.
Abstract Background Anode heel effects have been shown to cause a non‐uniform distribution of X‐ray photon fluence, and anode angle could cause focal spot size variations across field. However, no previous study has investigated their effects on image quality metrics in radiography.

Enhancing Fatigue Crack Growth Resistance in Heterostructured Aluminum Bimetals by Tailored Interface Design

open access: yesAdvanced Engineering Materials, Volume 28, Issue 18, 23 September 2026.
Different Al/Al bimetals with a single engineered interface reveal how mechanical mismatch governs fatigue crack growth under cyclic loading. Additionally, loading–unloading–reloading tests link the microyielding behavior to the fatigue crack growth resistance, while crack‐path analysis reveals toughening mechanisms at the interface, highlighting ...

Facilitated Phase Transformation for Improved Performance of Earth‐Abundant Disordered Rocksalt Materials

open access: yesAdvanced Energy Materials, Volume 16, Issue 35, 16 September 2026.
As demand for Li‐ion batteries grows, Mn‐rich disordered rocksalt (DRX) oxides offer a sustainable, low‐cost alternative to scarce Ni and Co. During cycling, Mn‐rich DRX materials transform into a partial spinel‐like phase (𝛿) that improves rate capability and capacity.
