Direct Recycling of Cold Work Tool Steel Swarf into New Cutting Disks via Field‐Assisted Sintering

Advanced Engineering Materials, EarlyView.
Through a sintering method known as field‐assisted sintering technology/spark plasma sintering, cold work tool steel swarf can be directly recycled into new cutting disks. This method is capable of densifying the unconventional powder morphology of swarf, and it can also seal grinding contaminants, such as Al2O3, into the steel matrix.

Infrared anomalous Hall effect in SrRuO$_3$: Evidence for crossover to intrinsic behavior

, 2009
The origin of the Hall effect in many itinerant ferromagnets is still not resolved, with an anomalous contribution from the sample magnetization that can exhibit extrinsic or intrinsic behavior.

Development of SiC Nanocomposites Using Direct Ink Writing Process

Advanced Engineering Materials, EarlyView.
Herein, feedstock inks containing polycarbosilane and various concentrations of SiC nanoparticles (SiCnp) are investigated for fabricating ceramic matrix composites using a DIW 3D printing process. Characterization results from physical measurement, microstructure analysis, and thermal and flexural testing suggested that high‐performance CMC samples ...

3D quantum Hall effect of Fermi arcs in topological semimetals

, 2017
The quantum Hall effect is usually observed in 2D systems. We show that the Fermi arcs can give rise to a distinctive 3D quantum Hall effect in topological semimetals.

Linking Heat Treatment to Plastic Deformation in Pearlitic Steels Through Mesoscale Modeling

Advanced Engineering Materials, EarlyView.
Surface wear on rail and wheel steels results from surface deformation during use. This research uses mathematical models to forecast the plastic behavior of pearlitic steels, connected to the microstructure formed during heat treatment. While the cooling rate impacts the steels’ strength, the size of prior austenite grains and blocks does not ...

Thermodynamic ground and Berry-phase origin of the planar spin Hall effect

Physical Review Research
The thermodynamic ground of the spin transport is elaborated, demonstrating the Onsager's reciprocal relation. The latter is also confirmed by deriving the spin Hall effect and its inverse using the semiclassical theory and the linear response theory ...

Improved Strength and Corrosion Resistance of Ti–50Zr Alloy Through Heat Treatment

Advanced Engineering Materials, EarlyView.
This work systematically analyzes the effects of heat treatment on mechanical properties and corrosion behavior of Ti‐50Zr alloy produced via vacuum arc melting. Microstructure transforms from coarse lamellar α phase in as‐cast condition to fine and uniformly distributes acicular α′ phase in heat‐treatment state.
