Anisotropic Dielectric Breakdown Strength of Single Crystal Hexagonal Boron Nitride

open access: yes, 2016
Dielectric breakdown has historically been of great interest from the perspectives of fundamental physics and electrical reliability. However, to date, the anisotropy in the dielectric breakdown has not been discussed.

Thermoplastic cable insulation comprising a blend of isotactic polypropylene and a propylene-ethylene copolymer [PDF]

open access: yes, 2015
There is much interest in the development of replacement materials for crosslinked polyethylene (XLPE) that are both recyclable (i.e. thermoplastic) and capable of high temperature operation.

Enhancing Strength and Electrical Conductivity in Al–Zr–Sc Conductor Alloys Through Sn and Sr Microalloying and Two‐Step Aging Treatment

open access: yesAdvanced Engineering Materials, EarlyView.
Trace additions of Sn and Sr combined with a two‐step aging treatment are shown to enhance the microstructure and performance of Al–Zr–Sc conductor alloys. Strength and electrical conductivity increase concurrently through accelerated precipitation of fine Al3(Sc, Zr) precipitates and improved dislocation resistance, offering a cost‐effective pathway ...

The effect of disorder on transverse domain wall dynamics in magnetic nanostrips [PDF]

open access: yes, 2012
We study the effect of disorder on the dynamics of a transverse domain wall in ferromagnetic nanostrips, driven either by magnetic fields or spin-polarized currents, by performing a large ensemble of GPU-accelerated micromagnetic simulations. Disorder is

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Breakdown strength of glycerin in helical transmission line under hundred-nanosecond pulse

open access: yesAIP Advances, 2022
In this paper, a transmission line with five spiral-wires in parallel was designed. The transit time and the characteristic impedance of the transmission line are 200 ns and 14 Ω, respectively. Its slow wave coefficient is close to 13.

Phenomenological and Physically Based Modeling of Flow Stress and Strengthening Mechanism of Inconel 718

open access: yesAdvanced Engineering Materials, EarlyView.
Nickel‐based alloys are widely used in high‐temperature applications due to their excellent mechanical strength and oxidation resistance. However, properties such as high‐temperature strength and pronounced work‐hardening make them difficult to machine.

Power Frequency Breakdown Properties of LDPE-Doped Inorganic Nanoparticles

open access: yesMolecules
Although polyethylene is widely used in electrical insulation, it does not possess dielectric properties. It is therefore desirable to develop insulation materials with excellent dielectric properties.

Some Factors Effecting on the Dielectric Strength for (PVC- Kaolin) Composites [PDF]

open access: yesEngineering and Technology Journal, 2011
This research includes the effect of kaolin additions to the polymer matrix (PVC) and study some factors affecting to dielectric strength. The kaolin powder was added as percentage by weight (1,2,3 and 4%) to PVC, and the specimens formed by hot pressing

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

open access: yesAdvanced Engineering Materials, EarlyView.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.
