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 ...

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.
