“…[3][4][5][6][7][8][9] A higher joints strength of friction welded Ti/AISI 321 could be explained by the narrower reaction layer within 0.2 mm, which enhanced the joinability of friction welded Ti/AISI 321 stainless steel.…”

“…[1][2][3] The bonded couples should have leak tightness, easy fabricability and adequate strength for their efficacious use. 4) The conventional fusion welding techniques between Ti and stainless steel have resulted in the segregation of chemical species, stress concentration and formation of intermetallics. Especially, the combination between Ti and Fe alloys makes lots of intermetallic compounds to form at the interface because Ti and Fe are not completely soluble in solid state.…”

“…Although sound joints between Ti and stainless steel were successfully achieved using diffusion bonding method, [3][4][5][6][7][8] the brittle intermetallic compounds for example, Fe 2 Ti, FeTi and Fe 2 Ti 4 O, were widely formed in the interface. The diffusion bonded joints represented a lower strength than those of the base metals due to thicker intermetallic compounds.…”

The microstructures and mechanical properties of the friction welded pure Ti/AISI 321 stainless steel have been investigated. From the Ti side from the interface to the Ti base metal, the sequence of recrystallized grain, elongated grain and many twin embedded grain structures were observed. The reaction layers were formed within 0.2 mm thickness at the interface under the conditions of relatively longer friction time (t 1 ) and lower upset pressure (P 2 ). These reaction layers formed at the central interface were identified as (Fe, Cr) 2 Ti, FeTi 2 or Fe 2 Ti 4 O and -Ti, while those of the peripheral interface were identified as FeCr ( phase), (Fe, Cr) 2 Ti, FeTi and -Ti. The phase was restrictedly formed at the peripheral interface. Higher mechanical properties were acquired under higher upset pressure condition due to higher compressive force between bonded materials, smaller grain size and narrower thickness of reaction layer. Therefore, maximum ultimate tensile strength of these joints was approximately 420 MPa with the conditions of 400 MPa of P 2 and 0.5 s of t 1 .

“…6 When Ti alloys and stainless steels join mechanically, many intermetallic phases and different tension concentration areas occur at the intermediate of the joint, which then causes embrittlement and cracking. 7 When Ti directly welds to the stainless steel, intermetallic compounds such as FeTi and Fe 2 Ti can occur at the joining area due to Ti and Fe having very little fusion capabilities. Besides, TiC may form since Ti is a strong carbide-forming element and also occurrences of these compounds cause a crispiness in the joining area.…”

“…Muralimohan et al 11 welded Ti and 304L stainless steel by FW and through a nickel interlayer, which is deposited by electroplating on stainless-steel substrates with a range of 100±3 μm. The joining of dissimilar materials such as aluminium, titanium, magnesium and their alloys to stainless steels was reported in [1][2][3][4][5][6][7][8][9][10][11][12][13][14] , but very limited studies are reported for titanium and its alloy to stainless steel using FW. Moreover, using an interlayer in FW is very limited, because it is difficult to keep the intermediate layer in the intermediate zone.…”

The aim of this study was to friction weld dissimilar metals, i.e., Ti6Al4V to duplex stainless steel, with and without a nickel interlayer using a new method. The metallographic examinations of the weld were carried out and the strength of the joints was determined with tensile tests. The experimental results indicate that the Ti6Al4V and duplex stainless steel could be joined with a nickel interlayer. The highest tensile strength (605 MPa) was obtained and the tensile strength of the joint was significantly increased with an increase of the rotation speed and the friction pressure. Keywords: friction welding, titanium alloy, duplex stainless steel, nickel interlayer Namen te {tudije je varjenje s trenjem razli~nih materialov Ti6Al4V in dupleks nerjavnega jekla, z in brez vmesne plasti niklja, z uporabo nove metode. Izvr{eni so bili metalografski preizkusi zvara. Rezultati preizkusov ka`ejo, da je z vmesnim slojem niklja mogo~e spajati Ti6Al4V in dupleks nerjavno jeklo. Z nara{~anjem hitrosti vrtenja in pritiska pri trenju je mogo~e dose~i najvi{jo natezno trdnost (605 MPa), hkrati pa nara{~a tudi natezna trdnost spoja. Klju~ne besede: varjenje s trenjem, titanova zlitina, dupleks nerjavno jeklo, vmesni sloj niklja

Since the beginning of the 21st century, countries around the world have continuously increased their efforts in environmental governance. It has higher requirements for the performance of materials, not only to ensure that it is clean and nonpolluting, but also to maximize benefits. The mechanical properties and economic value of a single material can no longer meet the production needs of enterprises. Therefore, more people use composite materials to replace single materials. The use of composite materials not only can effectively respond to the concept of green development, but also reduces cost input to a lager extent. The composite of dissimilar metals can volatilize the respective advantages of the two materials. Common materials can be used to replace rare metals to reduce the use of precious metals. [1][2][3][4] World-renowned automobile companies such as Japan's Toyota and Honda are vigorously researching lightweight production technologies. Lightweight alloys (such as magnesium [Mg] alloys, aluminum [Al] alloys, etc.) could be used in place of steel in non-load-bearing structures. Mg alloys are one of the lightest metal materials so far, with a density of only 1.74 g cm À3 , which is about 2/3 of Al, 1/4 of zinc, and 1/5 of steel. They have high specific strength, specific stiffness, good damping performance, and easy recycling and other advantages, known as the "21st century green engineering metal materials." Titanium (Ti) alloy is expensive and its processing performance is relatively poor. Steel has
