Measured gas desorption and electron cloud effects with an intense ion beam in a solenoid lattice

Physical Review Special Topics. Accelerators and Beams, 2008
Electron cloud and gas measurements were conducted in a solenoid lattice with a 10  μs, singly charged K^{+} ion bunch at an ion energy of 0.3 MeV and currents of 26 and 45 mA.

Effect of neutral gas temperature on low-pressure RF argon discharges: A fluid simulation [PDF]

AIP Advances
Based on plasma fluid theory, using the drift-diffusion approximation, a one-dimensional fluid model is established for the plasmas in low-pressure RF argon discharge between parallel-plate electrodes.

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

Experimental Evidence of Electron‐enhanced Interfacial Thermal Conductance Through Two‐Dimensional Electron Gas

Advanced Electronic Materials
It has been a persistent challenge to experimentally distinguish the contribution of electron‐phonon coupling on interfacial thermal conductance from phonon‐dominated pathways.

The Charging-Up Phenomenon in Gas Electron Multiplier Detector

Particles
Gas Electron Multiplier (GEM) detectors have become an indispensable component of modern tracking systems. The heart of a GEM detector is a thin polyimide foil (∼50 µm) clad with copper (∼5 µm) on both sides and containing an array of regularly spaced ...

Improvement of NO2 Sensing Properties in Pd Functionalized Reduced Graphene Oxides by Electron-Beam Irradiation

Frontiers in Materials, 2019
Herein, we present the effect of electron-beam irradiation (EBI) on the gas-sensing properties of Pd-functionalized reduced graphene oxide (RGO). Scanning electron microscopy, transmission electron microscopy, and X-ray photoelectron spectroscopy were ...

Creep Properties and Deformation Mechanism of Additively Manufactured NiAl‐CrMo Composites

Advanced Engineering Materials, EarlyView.
Additively manufactured NiAl‐CrMo composites contain numerous interfaces and cell boundaries that control their creep response. At 700°C under high applied stress, creep is dominated by dislocation‐controlled power‐law mechanisms. At 800°C–900°C and lower stresses, creep is primarily diffusion‐controlled along cell boundaries.

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

Advanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
