Generalized finite-element models for the electron-beam treatment of the surface of materials with significantly
different thermophysical properties have been created, allowing the calculation and optimization of
process conditions. For products of different geometries, taking into account the thermodynamics of the
process and the temperature dependences of the properties of materials, controlling the electron beam
geometry and the process cycloramas, the ranges of energy parameters of electron beam processing have
been optimized.
Finite-element modeling of surface heating during electron-beam processing was carried out for a flatshaped
part by a stationary source with scanning, as well as when exposed to linear beam movement without
scanning. To optimize electron beam reflow during soldering, a thermodynamic finite-element model is
proposed that takes into account the geometric features of the cutter inserts and the thermophysical properties
of their constituent materials. It is shown that taking into account the temperature dependence of the
thermophysical properties of the materials makes it possible to realize electron beam processing schemes
with a shorter duration of exposure to a beam of greater power.
