In this paper the simulation of electron beam welding of Inconel 718 thin plates by a moving linear heat source is considered. Regression models for the molten pool geometry characteristics, depending on the electron beam ...
In this paper an experimental study of the geometrical characteristics of the cross-sections of the thermally affected areas obtained by electron beam welding joints of carbon steel grade 45 is made. The thermally affected ...
The quality of EBWelds, realized by a 90° deflected Electron Beam, depends on operator defined parameters of the welding equipment, like gun voltage and current, beam centering, focus current(s), bending magnet current, welding ...
We present the design, simulation and analysis of 400 kW sheet beam gun. The beam optics, beam envelop and the magnetic field of the gun is designed and then simulated in CST PS. 100% beam transmission is achieved at the target ...
We fabricated high performance cold cathode electron beam with carbon nanotube (CNT) emitters. High performance cold cathode electron emitters show more than 150 mA electron emission current and long-time operational stability. ...
In the paper is presented multicolumn e-beam lithography (MCL) system intended generally for production of templates.
The system was designed in two versions: with Schottky emitter and LaB6/CeB6 emitter.
System with Schottky ...
Cobalt, as one of the “critical” and “strategically important” metals, plays a key role in the contemporary development of the world’s industry. Cobalt has specialized applications where it is currently impossible ...
