“…In order to solve these problems, many welding methods have been practiced to investigate the joining between titanium alloys and stainless steels, mainly including brazing welding [7,[16][17][18][19][20], laser welding [2,5,6,[21][22][23][24][25], electronbeam welding [26][27][28][29][30][31], diffusion bonding [32][33][34][35][36], explosive welding [37][38][39][40], and friction stir welding [41][42][43][44][45][46][47]. Cu-based and Ag-based fillers were usually used to braze titanium/steel joints, while scattered brittle intermetallics, such as (Fe,Cu)Ti, Cu 4 Ti 3 , and CuTi [20,48] and Cu 4 Ti and CuTi 2 [7], were induced to the interfaces which were detrimental to the mechanical properties of the joints, and maximum possible tensile strength of the joints was found to be no more than 200 MPa [16][17][18][19][20]…”

“…Cu-based and Ag-based fillers were usually used to braze titanium/steel joints, while scattered brittle intermetallics, such as (Fe,Cu)Ti, Cu 4 Ti 3 , and CuTi [20,48] and Cu 4 Ti and CuTi 2 [7], were induced to the interfaces which were detrimental to the mechanical properties of the joints, and maximum possible tensile strength of the joints was found to be no more than 200 MPa [16][17][18][19][20]48]. Without the interlayer, sound joints are hard to be obtained by direct laser welding or electronbeam welding because of continuously distributed brittle TiFe intermetallics and high residual stress at the welding pool [21,25,[49][50][51][52]. Continuous wave laser was used to weld titanium and stainless steel, while Fe 0.2 Ni 4.8 Ti 5 , Cr 2 Ti, and NiTi phases were formed which resulted in extensive cracking at the interface [13].…”

“…Continuous wave laser was used to weld titanium and stainless steel, while Fe 0.2 Ni 4.8 Ti 5 , Cr 2 Ti, and NiTi phases were formed which resulted in extensive cracking at the interface [13]. By adjusting the beam offset toward the titanium alloy side, tensile strength of the joint can be improved, but FeAl, FeTi, Fe 2 Ti, and Ti 5 Fe 17 Cr 5 phases still exist at the interface [25]. As welded by laser welding, when joining titanium alloy and stainless steel by electron-beam welding without an interlayer, TiFe phases led to great brittleness and the joint cracked spontaneously under thermal stress [52].…”

High-quality joints between titanium alloys and stainless steels have found applications for nuclear, petrochemical, cryogenic, and aerospace industries due to their relatively low cost, lightweight, high corrosion resistance, and appreciable mechanical properties.is article reviews diffusion bonding between titanium alloys and stainless steels with or without interlayers. For diffusion bonding of a titanium alloy and a stainless steel without an interlayer, the optimized temperature is in the range of 800-950°C for a period of 60-120 min. Sound joint can be obtained, but brittle FeTi and Fe-Cr-Ti phases are formed at the interface. e development process of a joint mainly includes three steps: matching surface closure, growth of brittle intermetallic compounds, and formation of the Kirkendall voids. Growth kinetics of interfacial phases needs further clarification in terms of growth velocity of the reacting layer, moving speed of the phase interface, and the order for a new phase appears. e influence of Cu, Ni (or nickel alloy), and Ag interlayers on the microstructures and mechanical properties of the joints is systematically summarized. e content of FeTi and Fe-Cr-Ti phases at the interface can be declined significantly by the addition of an interlayer. Application of multi-interlayer well prevents the formation of intermetallic phases by forming solid solution at the interface, and parameters can be predicted by using a parabolic diffusion law. e selection of multi-interlayer was done based on two principles: no formation of brittle intermetallic phases and transitional physical properties between titanium alloy and stainless steel.

“…Joining of metallurgically incompatible Fe and Ti alloys by conventional fusion welding methods poses difficulties due to the formation of FeTi and Fe 2 Ti type intermetallic phases and various secondary phases leading to embrittlement of the weld interface [2]. To circumvent this problem, author's have used explosive cladding process to join Ti-5Ta-2Nb, an + Ti alloy and 304L SS for an important industrial application in the spent nuclear fuel reprocessing [3].…”

This paper addresses to the dissimilar laser welding of AISI 304 and AISI 1010 steel thin sheets. Cracks-free dissimilar edge fillet welds have been conducted using a Nd: YAG laser. Geometrical, micro structural, chemical and mechanical proprieties of the welds were investigated using electron microscopy, EDS and tensile test assisted by digital image correlating. The proper results were achieved at an energy density of 88 J/mm 2 using a 0.4 mm laser spot diameter. An austenite-ferrite structure characterizes the weld bead and the precipitation of the chromium carbide at the grain limits was observed in the heat affected zone. Good tensile behaviour was obtained; dissimilar joint was fractured on the carbon steel side at 482 MPa and 0.35 stain.
