“…To eliminate this problem, it is customary in world practice to use barrier layers created between steel and titanium, which protect against their mixing during welding. The recommended materials of such layers include vanadium [9], niobium [9], copper [9,10], nickel [11], etc. The choice of the layer depends on the welding technique, the type of joint, performance, etc.…”

This paper reports a study into the regularities of interphase interaction, features in the formation of intermetallic phases (IMPs), and defects when surfacing steel on titanium in four ways: P-MAG, CMT, plasma surfacing by an indirect arc with conductive wire, and PAW. A general tendency has been established in the IMP occurrence when surfacing steel on titanium by all the considered methods. It was determined that the plasma surfacing technique involving an indirect arc with conductive wire is less critical as regards the IMP formation. That makes it possible to obtain an intermetallic layer of the minimum thickness (25...54 μm) in combination with the best quality in the formation of surfaced metal beads. Further minimization of the size of this layer is complicated by a critical decrease in the heat input into the metal, which gives rise to the capability of the surfaced metal to be collected in separate droplets. The formation of TiFe2, TiFe, and the α-Fe phase enriched with titanium in different percentage compositions has been observed in the transition zone of steel surfacing on titanium under different techniques and modes of surfacing. The study has shown the possibility of formation, in addition to the phases of TiFe2 and TiFe, the Ti2Fe phase at low heat input. The technique of plasma surfacing by an indirect arc with conductive wire minimizes the thermal effect on the base metal. When it is used at the border of the transition of the layer of steel surfaced on titanium, the phase composition and structure of the layers in some cases approach the composition and structure of the transition zone of the original bimetallic sheet "titanium-steel" manufactured by rolling. A layer up to 5 μm thick is formed from the β phase with an iron concentration of 44.65 % by weight and an intermetallic layer up to 0.2...0.4 μm thick, close in composition to the TiFe phase. The next step in minimizing the IMP formation might involve the introduction of a barrier layer between titanium and steel.

“…Caligulu, et al [15][16][17] welded AISI 4340-2205 steels and studied the impact of rotation speed and friction time, use the X-ray radiographic tests and found the weldability. Kirik, et al [18] connected AISI 2205 to Ti6Al4V with and without nickel interlayer. However, many researches have been reported up to date on 2205 DSS jointed by FW as mentioned above; nevertheless, studies concerning dissimilar FW 2205 DSS and 1045 MCS is very scarce.…”

This study investigated the microstructure and mechanical properties of frictional welded joints between SAF 2205 duplex stainless steel and AISI 1045 medium carbon steel. The welded joints were fabricated by varying the friction pressure, friction time, and keeping the forging pressure, forging time and rotational speed as constant to obtain a constant range of welding temperature (780-800 °C). The results revealed that as the friction pressure increases and friction time decreases, weld interface hardness value, tensile strength and ductility increases. Also the hardness profiles present that weld interfaces exhibit higher hardness values than that of the two base metals. It was found that the highest efficiency of weld joint achieved was 93%, while the lowest was 76%. In addition, all welded specimens failed in the weld region. The microstructure analyses were carried out using optical microscopy and scanning electron microscopy equipped with energy dispersive spectroscopy.

This study investigates the effect of pressure (burn‐off and forging) on the mechanical properties of the joint between a wear‐resistant tool steel and a low‐alloy steel using linear friction welding. The authors have previously demonstrated the feasibility of joining these dissimilar materials, but the impact of pressure on the mechanical properties of the bimaterial joint remains unclear. To address this, weld samples are prepared using different pressures and are characterized through microstructural analysis, microhardness, tensile testing, and fractography. The results show that the strength of the joint between the wear‐resistant tool steel and the low‐alloy carbon steel increases as the pressure increases up to a certain point, after which a decrease is observed. The highest joint strength is achieved at a pressure of 360 MPa. The microhardness profile measurement reveals a distinct transition zone at the interface between the two materials, with varying hardness values. The hardness of the low‐alloy carbon steel increases near the interface, while that of the wear‐resistant tool steel decreases. This transition zone is found to be narrower at higher pressures. Microstructural characterization shows that the grain structure near the interface differs from that of the starting base materials.
