In this article quasi steady-state two-dimensional heat model is implemented for the simulation of the temperature distribution in the cast copper ingots through electron beam drip melting. Regression models are estimated ...
This article discusses a modeling approach for the obtained by electron beam welding molten pool shapes, which is based on experimental data, type mathematical function and regression analysis. The process of electron beam ...
Neural network models for the dependence of the geometry characteristics of welds from 38Cr2Ni2Mo high-strength steel, obtained at electron beam welding in presence of longitudinal beam deflection oscillations, are estimated. ...
In this paper the contrast and sensitivity characteristics are investigated concerning the negative tone electron beam resist HSQ (hydrogen silsesquioxane) and the positive tone SML300 electron beam organic resist, designed ...
Thin films of tungsten oxide are obtained at different technological parameters using electron beam evaporation process. Their optical and structure properties are investigated and the relation with process parameters is discussed. ...
Experimental results (four series of experiments) for EBW of two types of steel – high strength steel of 38Cr2Ni2Mo type and stainless steel are obtained and used for the estimation of models, describing the dependencies ...
The characterization of the radial and the angular space distribution of particle trajectories (or respective current distributions) in powerful electron beams is an actual scientific and practical task, connected with the ...
The conventional systems for control of throughout welds used beam current, that is passing through the crater in the liquid metal to the space on the back side of sample. In this paper a collector, situated not opposite the ...
Measurements of fluctuations of the ion current, collected by the plasma, generated during electron beam welding and treatment of the acquired data with modern digital methods are executed. Through the application of Coherent ...
