Рентгеноструктурный анализ аддитивно полученных образцов из титанового сплава ВТ6 и их сварных соединений

Abstract

The structure of Ti-6Al-4V alloy parts obtained by Selective laser melting and their electron-beam welded joints has been investigated using X-ray analysis. In this study, the Bead on Plate welding imitated of welded joints and produced a three welding zones such as the fusion zone, the heat affected zone and the base metal in the additive manufactured material. The results of the research show that the structure of as-built metal and their welded joint consists of α/α'/β-phases. The microdistortions of the crystal structure of the welded joint are lower, and the volume fraction of β-phase is higher than the as-built material
