Trustworthy Multimodal Attention Framework for Creep Rupture Life Prediction Under Data‐Scarce Conditions: A Case Study on IN718

Advanced Science, EarlyView.
An attention‐based multimodal deep learning framework is developed to predict the creep life of Ni‐based superalloys by fusing processing parameters with microstructural micrographs. The model achieves high accuracy (R2 = 0.92), aligns with metallurgical principles by capturing δ‐phase influence, and incorporates uncertainty quantification, offering a ...

Grain Boundary Structure Ordering via Electroshock Treatment Enhances Strength‐Ductility Synergy

Advanced Science, EarlyView.
Electroshock treatment triggers atomic rearrangement, transforming disordered grain boundaries into ordered states without inducing recrystallization. This grain boundary ordering effectively relieves strain concentration and strengthens boundaries, enabling a simultaneous improvement in both strength and ductility.

Engineered Allosteric Biosensor for In Situ DNA Glycosylase Detection in Neuroblastoma Risk Stratification and Drug Resistance Monitoring

Advanced Science, EarlyView.
An engineered allosteric biosensor (UUU‐DZ‐tFNA) was developed, in which UDG specifically recognizes and activates a DNAzyme to achieve signal cycle amplification in a sequentially activatable mode. UUU‐DZ‐tFNA achieves in situ UDG detection across multiple biological levels and facilitates risk stratification and drug resistance monitoring of NB ...

Revisiting Graphite Electrodes for Electric Arc Furnaces: Three‐Dimensional Microstructural Heterogeneity as a Design Parameter for Fracture Resistance

Carbon Innovation, EarlyView.
Graphite electrodes are revisited as strategically important carbon materials for electric arc furnace steelmaking. By correlating three‐dimensional microstructural complexity with fracture energy, this work reveals a fundamental trade‐off between graphitization and energy dissipation, providing a data‐driven framework for the rational redesign of ...

Hydrogen‐Enhanced Stress Corrosion Cracking of Wire Arc Additive Manufactured Inconel 625 Superalloy in NaCl Solution: Mechanism of Synergistic Degradation

Materials and Corrosion, EarlyView.
Hydrogen‐enhanced SCC of WAAM Inconel 625 in 3.5 wt.% NaCl solution. Hydrogen charging reduces passive film stability (lower corrosion potential) and promotes pitting at Laves phase/matrix interfaces. Stress corrosion cracks propagate along Laves‐rich regions, leading to quasi‐cleavage brittle fracture.
