Ultrahigh strength triggered by BCC and B2 eutectic-phase interfaces in a novel FeCrVNiAl high-entropy alloy

Materials Research Letters
The strength−ductility tradeoff and composition homogeneity have been the obstacles to obtaining advanced structural alloys. To overcome the limitations, we develop a novel coherently eutectic high-entropy alloy, i.e. Fe30Cr15V15Ni20Al20.

P‐T Uncertainty in Subsolidus Metamorphic Systems: Sources, Patterns and Controls

Journal of Metamorphic Geology, EarlyView.
ABSTRACT Phase equilibrium modelling of metamorphic rocks is subject to multiple, superimposed sources of uncertainty that affect pressure–temperature (P$$ P $$‐T$$ T $$) estimates, making it difficult to independently distinguish and evaluate the contribution of each source.

The Evolution of Interest‐Rate Models: From the Yield Curve to the Swaption Cube

Journal of Economic Surveys, EarlyView.
ABSTRACT Interest‐rate modelling is often taught as a catalogue of competing stochastic equations, obscuring why models were created and why modern sell‐side desks use several simultaneously. This survey reorganises the field around five layers of a pricing architecture: curve construction; arbitrage‐free dynamics; volatility‐smile representation ...

Strain relaxation in heteroepitaxial films by misfit twinning. I. Critical thickness

, 2007
Based on the dislocation theory of twinning, an analytical solution is given to determine the critical thickness of the misfit twin formation in an epilayer with different elastic constants from its substrate.

Synergistic B/Si Microalloying Induced Wear Resistance Improvement in FeCoNiCrCu High‐Entropy Alloy Coatings Prepared by Annular Oscillating Laser Deposition

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT To address the insufficient wear resistance of high‐entropy alloy (HEA) coatings under extreme conditions, FeCoNiCrCu and FeCoNiCrCuB0.03Si0.03 microalloyed coatings were fabricated via annular oscillating laser deposition. This work systematically investigated the effects of synergistic B/Si addition on their phase composition, microstructure,

Unlocking the Potential of Machine Learning for Advanced Single‐Atom Catalysts Design in Promoting Electrochemical CO2 Reduction

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Electrocatalytic CO2 reduction reaction (CO2RR) represents a pivotal pathway for the promotion of carbon neutrality and the preparation of highly valuable chemicals. To improve the product selectivity and catalytic efficiency of CO2RR, single‐atom catalysts (SACs) offering highly efficient atomic utilization rates and adjustable electronic ...

Misfit Dislocations at Mismatched Epitactic Heterojunctions

, 1990
The formation and structures of misfit dislocations are significant factors in understanding heteroepitaxy of lattice-mismatched materials. In this study, GaAs/Si, CoGa/GaAs and ErAs/GaAs heterojunctions in materials grown by molecular-beam epitaxy have ...
