“…The formation of IMC layer at the weld interface was inhibited, and the uniform and good interfacial microstructure was promoted. Prasanthi et al [ 201 ] studied the effect of heat preservation treatment on the internal structure of welded joints. The width of the intermetallic phase region containing FeTi and Fe 2 Ti gradually increased with the increase in temperature.…”

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

“…If the intermetallic zone is brittle it may lead to having weld failure soon. Prasanthi et al [14] successfully welded mild steel with titanium rod of ϕ10mm x100mm size using the FW process. Through their study, they con rmed the formation of ne Fe-Ti intermetallic phase at the weld interface and the hardness of 350 VHN was obtained at the interface.…”

This work describes the effect of newly introduced faying surfaces on the microstructure and the mechanical properties of dissimilar weld joints of AA6063 and AISI304L alloys that fabricated through the rotary friction welding process (RFW). The experiments were done as six different experimental methods ('A' to 'F') at 1300 rpm rotation, 18 MPa friction pressure (FP), 24 MPa upset pressure (UP) and 5 sec friction time (FT) with the faying surfaces of hemispherical bowl and thread of 1 mm pitch on the weld specimens. The fabricated joints and the weld zones were characterized by macro and micro-study, Energy Dispersive X-ray Spectroscopy (EDS) spectrums, tensile properties, Vickers microhardness, impact toughness and fractography. The results showed that these faying surface modi cations strengthen the bonding between the weld specimens and in uences the performance of the joints. The hemispherical bowl showed better results than the threaded surfaces. Axial shortenings were within the acceptable limit in the range of 20-27 mm. Macro and microstructural studies showed the defect-free weld joints and the strong bonding between AA6063 and AISI304L alloys. The hemispherical faying surface on AISI304L alloy formed a U-shaped weld interface (WI) in the dissimilar joints. EDS proved the formation of the Fe-Al intermetallic and the element 'O' at weld zone. The joint e ciency for all the methods was around ≥ 100%. Maximum tensile strength was recorded as 238 MPa for method 'F'. The threaded surface showed good hardness property nearby WI and method 'A' yielded maximum impact toughness for the joint.

“…From the micrograph, it is observed that the interface was free from weld defects, and the diffusion distance for Fe and Ti was estimated to be 2 mm on both sides of the interface. (Prasanthi et al, 2015). The temperature generation in the interface regions is analyzed radially and circumferentially and the observed values show the heat moves toward the center when the Reynolds number is increased.…”

PurposeIn friction welding of dissimilar joint method, few material compositions are not possible to weld effectively. For better dissimilar metal joining in friction welding, the interlayer techniques are used by the third metal to increase the diffusion for suitable metal bonding. The interlayer metals are popularly held by coating, foils, sheet and solid rod form. The coating method needs more care for surface preparation with special coating equipment with high workmanship. In case of foil as intermediate metal, more care is neededfor holding between the metal; most of the time this technique has the possibility of failure by peeling off from the contact surface during high speed rotation with pressure during friction generation.Design/methodology/approachIn this investigation, a copper coin was machined to a suitable size (transition fit) to suit the recess inside the SS rod. The mating surfaces of Cu coin, SS rod and Ti alloy were machined, polished to mirror finish and handled in friction welding machine. The purpose of the transition fit between the coin and SS rod is for holding the same intact before the beginning of the process.FindingsSuccessful joint was achieved with good joint strength at less time. Empirical models were established to fin out the joint strength at any given parameter within the range of investigationResearch limitations/implicationsThe models developed can be used only within the range of investigation considered for experimentation.Practical implicationsThe paper includes implications for the development of a method of joining any dissimilar jointsOriginality/valueIn this investigation, a copper coin was machined to a suitable size (transition fit) to suit the recess inside the SS rod.
