It is demonstrated that severe lattice distortion and coherent nanoprecipitates overcome the strength–ductility dilemma and mitigate discontinuous plastic flow (DPF) at 4.2 K. Such microstructural design enhances both thermal and athermal stress components, leading to exceptional mechanical performance.

A parametrically‐Conditioned Deep Learning Surrogate for Coherent Spinodal Decomposition
Spinodal decomposition of strained alloys with cubic anisotropy is reproduced by a Convolutional Recurrent Neural Network, taking the misfit parameter as explicit input to return different morphologies. The predicted composition fields match phase‐field simulations over a broad range of parameters, allowing to reconstruct the full phase diagram.

Where Can Aluminum Go When Batteries Die?
Battery‐derived aluminum is transformed from contaminated waste into an alloying resource for high‐performance Fe‐based alloys. Through controlled Al content and processing, dual‐phase austenite/ferrite microstructures with TRIP‐like behavior are achieved.

A Novel Approach for ∆K Estimation in the Fatigue Threshold Region Based on ΔKth and Kmax,th
ABSTRACT A novel procedure, proposed by Kujawski and Vasudevan 1, has been evaluated as an alternative to the ASTM E647 standard for determining the ∆Kth and Kmax,th thresholds. This method relies solely on the actual propagation of cracks, which occurs only when both thresholds are satisfied simultaneously. For long cracks, a more efficient estimation

Soldering Si3N4 to Invar42 by a localized heating process
Abstract This study investigates the soldering process for joining silicon nitride (Si3N4), a commonly used ceramic, to Invar42, a low thermal expansion alloy. The focus lies on analyzing interfacial reactions and evaluating the bonding performance of the Si3N4—Invar42 joint.

Synthesis and thermal properties of dense Si─Al─C─N‐based polymer‐derived ceramics
Abstract In the present study, aluminum‐modified preceramic silicon polymers were synthesized via chemical modification of a commercially available organopolysilazane using an aluminum amido complex. The incorporation of aluminum into the polymer structure and its effect on ceramization behavior and processability as well as the thermal and mechanical ...

Multicomponent Rare‐Earth Monosilicate Reactions With Calcium‐Magnesium Aluminosilicate
ABSTRACT High‐temperature reactions of multicomponent rare‐earth monosilicates (REMS) with calcium‐magnesium aluminosilicate (CMAS) were investigated at 1300°C for 24 h. Three compositional series were tested, each ranging from 1‐cation to 4‐cation REMS, with cations selected to interrogate compositional effects on CMAS reactivity. The final members of
