Electron-Beam Surface Treatment of Titanium Alloy Ingots. Part 1

Abstract

A scheme for electron-beam melting (EBM) is selected on the basis of analyzing and systematizing accumulated data for electron-beam treatment of an ingot surface. In order to minimize experimental work and to determine the main production parameters of the EBM process for titanium alloy ingots work is conducted for mathematical modeling of thermal processes within a treated ingot, and also mass transfer processes in a molten bath at an ingot surface. Dependences are plotted for the depth of ingot melted surface layer, and also the content within it of alloying elements on process production parameters (melting rate, specific power).
