“…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.…”

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.

Рассмотрены особенности соединения титанового сплава ПТ-3В со сталью 08Х18Н10Т диффузионной сваркой с применением промежуточного слоя из ультрадисперсного порошка никеля, получаемого термическим разложением формиата никеля Ni(COOH) 2 +2Н 2 О. Проведено сравнение структур сварных соединений данных материалов на наличие интерметаллидных фаз при сварке без промежуточных слоев и с никелевым промежуточным слоем при различных параметрах режима. Применение ультрадисперсного порошка никеля при температурах 965 и 890 °С приводит к образованию сплошного слоя твердых интерметаллидов. При температуре 790 °С диффузионная зона имеет многослойную структуру, отличающуюся от микроструктуры соединения сталь-титан, полученного без промежуточного никелевого слоя. Механические испытания сварных соединений на разрыв показали, что достаточные прочностные свойства достигаются при использовании промежуточного слоя из ультрадисперсного порошка никеля при пониженных температуре и давлении, исключающих интенсивный рост интерметаллидов. Наибольшие значения предела прочности достигнуты при температуре сварки 760…790 °С и составили в среднем 346 МПа. Библиогр. 13, табл. 3, рис. 4.
