“…[1][2][3] However, it is typically accompanied with technical challenges, because of chemical or physical property mismatch of the two materials involved, resulting in difficulties in microstructure prediction, fusion zone control, and insufficient weld penetration. Intermetallic compounds which are typically brittle would form at dissimilar metal joints, resulting from excessive solute dilution and inappropriate temperature evolution.…”

“…Intermetallic compounds which are typically brittle would form at dissimilar metal joints, resulting from excessive solute dilution and inappropriate temperature evolution. [2][3][4][5][6][7][8][9][10] A deep understanding of heat transfer in fusion welding of dissimilar couples is thus of crucial importance to advance the technology for future commercial use.…”

Pulsed laser butt welding of miscible dissimilar couple has been studied numerically based on a three-dimensional heat and mass transfer model. Driving forces of molten metal flow in the case of stainless steel and nickel are compared using dimensional analysis. Thermo-capillary convection due to surface temperature gradient is recognized as the dominating fluid flow. Temperature coefficients of surface tensions are varied to investigate the influences of the convection on heat and mass transfer phenomena in weld pool. The temperature fields at stainless steel and nickel sides are found to be asymmetric and are greatly affected by different Marangoni convections. Concentration of Ni increases as the temperature coefficient of surface tensions changes from negative to positive. The temperature coefficient of surface tension of stainless steel has greater impact on the weld pool configuration and element concentration than that of nickel. The obtained weld pool configurations are found to be dependent on Prandtl number and convection patterns.

“…Other authors seeking to join dissimilar materials have attempted to bypass the material properties issue by creating preformed mechanical features such as Lazarevic for an aluminum and steel joint, Balakrishnan for joining nylon to aluminum, Nishihara with aluminum and steel, and Evans with aluminum to steel [11][12][13][14]. Yet another alternative has been proposed of introducing a third material by using a combination of friction stir welding (FSW) and riveting.…”

a b s t r a c tTwo-sided friction stir riveting (FSR) by extrusion is an innovative process developed to rapidly, efficiently, and securely join dissimilar materials. This process extends a previously developed one sided friction stir extrusion process to create a strong and robust joint by producing a continuous, rivet-like structure through a preformed hole in one of the materials with a simultaneous, two-sided friction stir spot weld. The two-sided FSR by extrusion process securely joins the dissimilar materials together and effectively locks them in place without the use of any separate materials or fasteners. In this paper we demonstrate the process by joining aluminum to steel and illustrate its potential application to automotive and aerospace manufacturing processes.

“…Several studies on the use of SPS as a manufacturing technique for SiC materials have been published in the last decade [17][18][19][20][21][22]. In the field of materials joining, many studies have focused on metal-to-metal, ceramic-to-ceramic or ceramic-to-metal joints using conventional techniques [23][24][25][26][27][28].…”
