“…Plenty of research has been devoted to the welded joints production of titanium alloys with steel by implementation of various welding methods. Explosion welding [1][2][3][4][5][6][7][8][9] and diffusion welding [10][11][12][13][14][15] are the most common ways to obtain a permanent joint of titanium with steel. The main disadvantage of these welding methods is the geometric shape limitation of the welded parts.…”

“…At the same time, the production of titanium and steel compounds by fusion welding is complicated due to the formation of brittle intermetallides characterizing the metallurgical incompatibility of titanium and iron. In order to avoid the formation of brittle interlayers, many researchers use transition layers from other materials [13][14][15][16][17][18][19][20][21][22][23].…”

The possibility of obtaining a combined titanium-steel construction by directed energy deposition using vanadium or vanadium/nickel interlayers. Vanadium wire VnPr-1, nickel wire NP1 grade and welding wires Sv-08G2S, 316L, MSG NiFe-1 grades were used for deposition on the end of the titanium plate VT1-0. The use of vanadium as an interlayer deposited on titanium makes it possible to provide a joining with a stable structure, steady hardness distribution and acceptable manufacturability. The content of dissolved titanium in the vanadium layer negatively influence on the subsequent deposition of steel, nickel or iron-nickel alloy. Therefore, the titanium content was reduced to the level of ˂0.5% by deposition at least 4 vanadium beads. The results of tensile tests showed that all specimens failed in the elastic section mostly along the interlayers between vanadium and subsequent layers of low-carbon steel, nickel and iron-nickel alloys deposited on it. The only specimen was destroyed along the titanium-vanadium interlayer probably due to brittle ω–phase formation.
