Abstract
Complex works were performed to study the quality of wrought semi-finished products, manufactured from an ingot of VT9 titanium alloy. Electron beam remelting technology was used to produce ingots of 600 mm diameter and 1.5 m length, from which semi-finished products were manufactured in the form of hot-pressed rods of 315 mm diameter. Results of investigations of structurare and mechanical properties of semi-finished products in the form of hot-pressed rods are given. It is shown that the metal of the produced ingots and wrought semi-finished products meets the requirements of the standards after the respective heat treatment. Ref. 10, Tabl. 4, Fig. 3.
Keywords: electron beam melting; high-strength titanium alloy; ingot; chemical composition; structure; deformation; mechanical properties
