“…For instance, Al-Cu bimetallic joints were usually used for fabricating lead wire and cable electrical connectors in service requirement. [6][7][8][9][10] So far, various welding techniques have been applied to join the Al-Cu bimetallic sheet, including explosive welding (EXW), friction stir welding (FSW), and electron beam welding (EBW). Xiao et al 11 have utilized the EXW to join the Al-Cu bimetallic sheet.…”

Two sound joints of Al–Cu bimetallic sheet with 6.5 mm in thickness were obtained in Cu (upper)–Al (lower) and Al (upper)–Cu (lower) welding configurations via the electron beam welding and their distinct coupling models were developed to well understand their flow behavior of the molten pool and microstructure evolution mechanisms during the electron beam welding. For the electron beam welding of the Cu–Al bimetallic sheet, liquid Al and Cu flowed into each other and fully combined in the fusion zone and the interface zone under high-temperature environment, forming large amount of intermetallic compounds. For the electron beam welding of the Al–Cu bimetallic sheet, liquid Al was floating on the Cu substrate, while liquid Cu was flowing at the bottom of the molten pool and mutually combined with liquid Al at the interface, forming a relatively small amount of intermetallic compounds. Moreover, a part of liquid Al flowed back to the seam root under the influence of the Marangoni effect. Therefore, the fusion zone and the interface zone with various phase compositions were formed in these two Al–Cu bimetallic joints and the mechanical properties of the corresponding joints were determined. Furthermore, the average tensile strengths of Cu–Al and Al–Cu bimetallic joints were 59 MPa and 67 MPa, respectively. The fracture locations of these two joints were both at the edge of the fusion zone along the Al2Cu intermetallic compound interlayer. Moreover, the fracture characteristics of these joints were mainly cleavage fracture.

“…Dissimilar metal joining is employed in various applications requiring specific combination(s) of properties in order to reduce cost and materials usage. Many emerging applications in power generation and the chemical, petrochemical, nuclear, aerospace, transportation, and electronics industries increase the incidence/usage of joining of dissimilar materials via methods such as friction welding and friction stir welding [1][2][3]. Due to the different thermo-mechanical and chemical properties of the materials, the joining of dissimilar materials becomes more challenging than that of similar metals [2].…”

Tool steels are commonly used to cut metal materials due to their distinctive hardness, resistance to abrasion and deformation. However, tool steels are difficult to be joined using conventional fusion welding process. In this study, a thixotropic property of metal was utilised to butt-join an AISI D2 tool steel by using uncommon direct partial re-melting (DPRM) method. A high frequency of induction heating is used to apply the DPRM method. From the recent study, there are many methods in achieving the globular microstructure with the success of semi-solid joining process. Though, very less information on the microstructural effect of semi-solid joining on the mechanical properties was reported. This study aims to analyse the effect of uniaxial force on the microstructural evolution and mechanical properties of the thixo-joint of D2 tool steel. The microstructural analysis showed the diffusion occurred between the grains of the thixo-joint sample with 2.5 N uniaxial force. The maximum strength of the thixo-joint sample with force was 652 MPa. This was slightly higher than the as-received sample and the thixo-joint sample without force. The average hardness value of the thixo-joint sample was 400 HV due to the transformation of ferrite to the metastable austenite.

“…Ouyang et al 33 performed similar studies for butt FSW of Cu-Al6061 joints. Bisadi and coworkers [34][35][36][37] investigated the influence of FSW parameters including tool rotational speed, offset of pin and welding speed on the quality of welded sections, mechanical properties and microstructure of dissimilar Cu-Al5083 joints. Xue et al 38,39 also studied the mechanical properties, microstructure, initiation of defects in the nugget zone and formation of inter-metallic compounds in the interface of a copper-aluminum 1060 joint welded by the FSW.…”

Strength and load-bearing capacity of dissimilar joints welded by friction stir welding is one of the most interesting subjects for optimizing this recently developed joining technique. Hence, in this article, dissimilar butt weldments of pure copper with Al5083 are manufactured with different welding parameters (including pin rotational and tool offset). Then rectangular beam specimens containing right angle notches in the interface of joints were prepared from the welded plates and tested under threepoint bend loading to investigate the interface fracture strength of Al-Cu joints. The results showed the significant influence of welding parameters on the strength and load-displacement curves of the tested bimetals. It was shown that considering a suitable value for the offset of pin can increase the interface fracture strength. The highest fracture loads were achieved at moderately lower pin rotational speeds.
