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.

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.

Collimation with Hollow Electron Beams

Physical Review Letters, 2011
A novel concept of controlled halo removal for intense high-energy beams in storage rings and colliders is presented. It is based on the interaction of the circulating beam with a 5-keV, magnetically confined, pulsed hollow electron beam in a 2-m-long section of the ring.

Interaction of impurity distribution and groove at the micro-zone of solid/liquid interface in silicon

Materials & Design, 2022
Groove, as a special structure at the front of solid–liquid (S/L) interface, takes a great influence on the distribution of impurities for silicon. In this work, the interaction between grooves and impurities was studied, and the evolution model of ...

Electron beam calibration constants

Japanese Journal of Radiological Technology, 1978
Electron treatment beam calibration constants are tabulated in a convenient form for mean incident electron energies, Eo, of 6 to 21 MeV; and practical reanges, Rp, of 2.75 to 10.53 cm of water. Values of mean electron energy at depth Ed, chamber radius correction factors (Kp), and CE factors may be readily obtained from this chart.
