Copper diffusion rates and hopping pathways in superionic Cu2Se

期刊: ACTA MATERIALIA, 2021; 215 ()

The ultra-low thermal conductivity of Cu2Se is well established, but so far there is no consensus on the underlying mechanism. One proposal is that th......

Hidden role of intrinsic Sb-rich nano-precipitates for high-performance Bi2-xSbxTe3 thermoelectric alloys

期刊: ACTA MATERIALIA, 2021; 215 ()

Nanostructuring is a universal strategy to improve the figure of merit (zT) of thermoelectric (TE) materials by the substantial decrease of lattice th......

Damage accumulation during high temperature fatigue of Ti/SiCf metal matrix composites under different stress amplitudes

期刊: ACTA MATERIALIA, 2021; 213 ()

The damage mechanisms and load redistribution taking place under high temperature (350 degrees C), high cycle fatigue (HCF) of TC17 titanium alloy/uni......

A moire theory for probing grain boundary structure in graphene

期刊: ACTA MATERIALIA, 2021; 217 ()

Multiscale microscopy spanning the atomistic, moire, and meso scales has enabled engineering the equilibrium structure of graphene. However, temporal ......

Electrochemical grinding-induced metallic assembly exploiting a facile conversion reaction route of metal oxides toward Li ions

期刊: ACTA MATERIALIA, 2021; 211 ()

Conversion-type electrodes generally feature unstable cycling stability as an anode for Li ion batteries. In this work, however, we suggest that the w......

Ideal superelasticity in Ni-based Heusler alloys

期刊: ACTA MATERIALIA, 2021; 210 ()

The hysteresis that occurs during superelasticity caused by the stress-induced first-order martensite transformation is sometimes detrimental to the p......

Enhancement of vacancy diffusion by C and N interstitials in the equiatomic FeMnNiCoCr high entropy alloy

期刊: ACTA MATERIALIA, 2021; 215 ()

We present evidence of homogenization of atomic diffusion properties caused by C and N interstitials in an equiatomic single-phase high entropy alloy ......

Revealing DeNOx and DeVOC Reactions via the Study of the Surface and Bandstructure of ZnSn(OH)(6) Photocatalysts

期刊: ACTA MATERIALIA, 2021; 215 ()

Photocatalytic materials present a robust approach in tackling pollutants in the air. However, the involving reactions and their associated toxicity, ......

A novel 3D mixed-mode multigrain model with efficient implementation of solute drag applied to austenite-ferrite phase transformations in Fe-C-Mn alloys

期刊: ACTA MATERIALIA, 2021; 212 ()

A computational 3D model that accounts for both nucleation and interface migration is a very useful tool to monitor and grasp the complexity of micros......

Twinning pathways in Fe and Fe-Cr alloys from first-principles theory

期刊: ACTA MATERIALIA, 2021; 215 ()

Using density-functional theory, we determine the generalized stacking fault energy (GSFE) for the {1 (1) over bar 12} < 1 (1) over bar 11 > twi......

In situ studies of liquid-liquid phase separation, solidification sequence and dendrite growth kinetics in electrostatically levitated Ti-Y alloys

Melts of hypomontectic Ti75Y25, near-monotectic Ti70Y30 and hypermonotectic Ti60Y40 composition were undercooled and solidified using an electrostatic......

Influence of microstructure and atomic-scale chemistry on the direct reduction of iron ore with hydrogen at 700 degrees C

期刊: ACTA MATERIALIA, 2021; 212 ()

Steel is the most important material class in terms of volume and environmental impact. While it is a sustainability enabler, for instance through lig......

Synchrotron X-ray imaging and ultrafast tomography in situ study of the fragmentation and growth dynamics of dendritic microstructures in solidification under ultrasound

期刊: ACTA MATERIALIA, 2021; 209 ()

High speed synchrotron X-ray imaging and ultrafast tomography were used to study in situ and in real time the fragmentation and growth dynamics of den......

Near room-temperature formation of Cu3Sn: In-situ synchrotron X-ray diffraction characterization and thermodynamic assessments of its nucleation

期刊: ACTA MATERIALIA, 2021; 213 ()

The fabrication of Cu3Sn at near room temperatures and atmospheric pressure remains out of reach. We propose a novel concept to address this challenge......

In situ study of non-equilibrium solidification of CoCrFeNi high-entropy alloy and CrFeNi and CoCrNi ternary suballoys
