Effect of melt superheat treatment on solidification behavior and microstructure of new Ni–Co based superalloy

Journal of Materials Research and Technology, 2021
A new type of Ni–Co based superalloy was prepared by vacuum induction melting (VIM), and the effects of superheat on element distribution, dendrite segregation, and solidification microstructure refinement of the new Ni–Co based superalloy are revealed ...

Effect of Laser Heat-Treatment and Laser Nitriding on the Microstructural Evolutions and Wear Behaviors of AISI P21 Mold Steel

Metals, 2020
Laser heat-treatment and laser nitriding were conducted on an AISI P21 mold steel using a high-power diode laser with laser energy densities of 90 and 1125 J/mm2, respectively. No change in surface hardness was observed after laser heat-treatment.

Simulations of slow positron production using a low energy electron accelerator

, 2011
Monte Carlo simulations of slow positron production via energetic electron interaction with a solid target have been performed. The aim of the simulations was to determine the expected slow positron beam intensity from a low energy, high current electron

Homogenization behavior of IN 718 superalloy prepared by electron beam layered solidification technology

Journal of Materials Research and Technology, 2021
The homogenization behavior of IN 718 superalloy prepared by electron beam layered solidification has been investigated at 1150 °C. The set temperature was accurately corrected as 1149 °C by a compound method.

Early out-of-equilibrium beam-plasma evolution

, 2006
We solve analytically the out-of-equilibrium initial stage that follows the injection of a radially finite electron beam into a plasma at rest and test it against particle-in-cell simulations.

Three-dimensional analysis of the surface mode supported in \v{C}erenkov and Smith-Purcell free-electron lasers

, 2016
In \v{C}erenkov and Smith-Purcell free-electron lasers (FELs), a resonant interaction between the electron beam and the co-propagating surface mode can produce copious amount of coherent terahertz (THz) radiation.
