Ultrafast Solid‐State Synthesis of Chevrel Phases for Microstructure‐Enabled Thermoelectric Transport Optimization

ABSTRACT Chevrel phases are promising medium‐ to high‐temperature thermoelectrics owing to their structural stability and intrinsically low lattice thermal conductivity, yet prolonged high‐temperature synthesis causes grain coarsening and limits microstructural control. Here, we...

Texture evolution and tension–compression yield symmetry of AZ31 magnesium alloy during cyclic extrusion and compression: Experiments and polycrystal plasticity simulations

Cyclic extrusion and compression (CEC) was selected as a representative variable-strain-path process for mitigating tension–compression yield asymmetry in extruded AZ31 magnesium alloy. A machine-learning-assisted VPSC-dDRX(CA) framework was developed to characterize the associat...

Reaction-sequence-regulated Y2O3/t-ZrO2 coherent interfaces enable Y diffusion and YSTZ toughening in ceramic coatings on AZ91D magnesium alloy

As a prototypical structural metallic material, AZ91D magnesium alloy is widely used in aerospace and automotive applications due to its low density and high specific strength, but its poor surface durability remains a critical limitation. To enhance service reliability, ceramic...

Effects of Lanthanum Doping on Structural Evolution, Morphological Features, and Flux Pinning in FeSe0.5Te0.5 Single Crystals with Machine Learning Assistance

Abstract Single crystals of La x Fe 1− x Se 0.5 Te 0.5 ( x = 0, 0.02, 0.04, 0.06, 0.08) were grown using the self-flux method. A systematic investigation of the effects of La addition revealed changes in the lattice parameters, with the lattice parameter a decreasing and the latt...

Effect of Precipitated Particles on Corrosion Behavior of VCrFeTa0.1W0.1 and VCrFeTa0.2W0.2 Refractory High-Entropy Alloys

In this study, the influence of precipitated Laves particles on the metastable pitting of VCrFeTa0.1W0.1 and VCrFeTa0.2W0.2 refractory high-entropy alloys (HEAs) in 3.5 wt.% NaCl solution was investigated. Microstructures and corrosion behaviors were characterized by XRD, SEM, TE...
