“…SUS304 stainless steel has been commonly used as a base material for heat exchangers, coolers, microchemical systems, and other high-temperature, high corrosion-resistant thin-wall pipe and plated parts owing to its excellent corrosion resistance and heat resistance. Diffusion bonding [ 1 , 2 , 3 ] and diffusion brazing (referring to brazing in this study) [ 4 , 5 , 6 ] are widely used for joining stainless steel. Compared to diffusion brazing, diffusion bonding can form a high-quality joint by overcoming the formation of brittle intermetallic compounds (IMCs), chemical segregation, and accumulation of residual stress at the joint interface, owing to its characteristics of solid-state diffusion.…”

In this study, an amorphous Ni-13.4Cr-11.6P (mass%) alloy coating with a thickness of 30 μm was deposited on the surface of SUS304 stainless steel as a brazing filler metal to conduct brazing. The differential thermal analysis measurements indicate that the electrodeposited Ni-13.4Cr-11.6P alloy has a melting point of approximately 892 °C, which is almost consistent with that of the commercial BNi-7 filler metal. The microstructure, shear strength, and fracture mode of the brazed joint were investigated using an electron probe X-ray microanalyzer, a scanning electron microscope, an optical microscope, and a universal testing machine. The results showed that the brazed filler metal is filled between the SUS304 stainless steel plates without any flaws in the brazed seam. The P-containing phases, i.e., the Cr-P rich phase and the (Ni,Fe)3P phase, were formed in the brazed seam. The shear strength of the brazed joint obtained in this study is 59.0 MPa. The fracture occurs in the brazed filler zone, where the brittle P-containing phases are present. Galvanic current measurement results showed that the brazed Ni-13.4Cr-11.6P alloy coating has a better corrosion resistance than that of the brazed Ni-11P alloy coating, which can be attributed to the formation of a large amount of Ni-Fe solid solution and Cr-P rich phase in the top layer of the brazed Ni-13.4Cr-11.6P alloy coating.

“…These Ti-Fe intermetallics are highly brittle, severely decreasing the strength and plasticity of Ti alloy-SS joint. [4,5] Thus, the Ti alloy-SS joint formed using direct welding was greatly brittle and easy to crack. To minimize the formation of brittle Ti-Fe intermetallics, several methods have been proposed and demonstrated in various reported works.…”

“…The possibility of joining distinct materials is a very attractive opportunity in the assembly and design of high-performance components for high-duty technological applications, such as in the automotive or in the aeronautic field [1]. Many of the structural elements in pressure vessels, spacecraft, and transport applications, as well as in offshore and nuclear structures are made of welded joints [2][3][4]. The coupling of different materials is very intriguing as it is possible to take advantage of the best properties of each material and build components with good structural and lightweight characteristics, but, on the other hand, it represents a challenge because new phenomena, arising from their interaction, must be taken under consideration [5].…”

Our study will be focused on stainless steel AISI 304—carbon steel ASTM A105 joints obtained by rotary friction welding and on their fatigue corrosion behavior in different testing environments. As a first thing, the joints will be characterized by microscopy and electrochemical techniques. The manuscript will then describe the optimization of the experimental setup and the validation of the testing procedure. After that, the fatigue behavior of the joints will be tested in different aggressive environments. This study pointed out that it is possible to build a simple and low-cost setup for the study of fatigue corrosion behavior of dissimilar joints while exploiting in situ electrochemical measurements to follow the fatigue corrosion process.
