The microstructure, mechanical properties and element distribution in an electron-beam welded joint of dissimilar metal compounds (TiNi/Ti6Al4V) have been studied. To prevent crack formation, niobium was introduced to the compound as a filler material. The welding line preheating and electron-beam deviation toward the Ti6Al4V alloy were used. It was shown that fracturing of the welded joint occurs within the fusion zone and is characterized by a mixed ductile-brittle behavior.

Key words
