Abstract
A comprehensive study was carried out to assess the quality of deformed semi-finished products manufactured from an ingot of the VT8 titanium alloy. Using electron beam remelting technology, 400-mm-diameter ingots were produced, from which semi-finished products in the form of hot-forged bars of 200 mm in diameter and disks of 440×145 mm were fabricated. The paper presents the results of investigations of the structure and mechanical properties of the obtained semi-finished products. It is shown that the metal of the produced ingots and deformed semi-finished products meets the requirements of the applicable standards.
Keywords: electron beam melting, heat-resistant titanium alloy, ingot, chemical composition, structure, deformation, mechanical properties
