Effect of Electron Beam Welding and Heat Treatment on the Structure and Properties of Technical Titanium with an Alloying Dope of Boron

Svitlana Hryhorenko, Valery Ju. Belous

The study discussed in the article included the analysis of features characterising the formation of an electron beam-welded joint made of a titanium alloy (Ti–TiB). The study also involved the investigation of the effect of heat treatment on structural-phase transformations in the weld metal and in the heat affected zone. The heat treatment of the welded joints resulted in the decomposition of the metastable phase, the distribution of boron particles in the structure as well as the increase in the structural homogeneity, leading to the improvement of mechanical properties.
