Abstract

In this article, the effect of heat treatment on the phase composition and structural state of welded joints of an experimental highly-doped titanium alloy, made by argon-arc and electron-beam welding, was investigated. As a result of the heat treatment of welded joints at a temperature of 690 ° C, the structure of the near-seam zone is stabilized. However, in order to fully restore the plasticity of the welded joint with the formation of alpha-phase globules of a simple structure in the structure of the near-seam zone, a higher heat treatment temperature is required.
