“…3a that the weld interface formed at 950 °C exhibited the formation of intermetallic compounds (IMCs). Detailed discussion on the nature of these IMCs and their formation can be found in (Muhammad Samiuddin et al, 2021;Samiuddin et al, 2021). In the light of EDX point analysis, it is suggested that most of the IMCs were Cr-rich carbides as shown in Fig 3d . Similar results were also reported in several publications (Muhammad Samiuddin et al, 2021;Samiuddin et al, 2021).…”

“…With such extravagant properties, researchers are now compelled to explore the weldability issues associated with CoCrNi MEA. Samiuddin et al (2021), explored the weldability of CoCrNi MEA with SUS 304 stainless steel and concluded that high diffusion bonding temperature embraced defect-free joints which consequently induced maximum shear strength. Du et al (2021) successfully performed diffusion bonding on FGH 98 (Ni-based superalloy) and CoCrNi MEA by utilizing Ni interlayer and achieved maximum shear strength of 592 MPa at 1150 °C (Du et al, 2021).…”

The study mainly focused on examining nanomechanical properties and corrosion behavior of the weld interface formed by diffusion welding of CoCrNi MEA and SUS 304 stainless steel. Three different bonding temperatures (i.e. 950 °C, 1000 °C, and 1050 °C) were utilized in producing diffusion welded joints. The influence of bonding temperatures on nanomechanical properties of the weld interface was characterized through Nanoindentation tests under various loads (i.e. 20 mN to 100 mN). Additionally, electrochemical properties of the weld interface were also examined using a 0.5 M HCl solution. Results clinched that with the increase of bonding temperature significant suppression in carbide formation occurred along with the weld interface. This instigated a reduction in nano hardness and elastic moduli which resulted in maximum elastic recovery along with the weld interface. The indentation size effect was also evident below 40 mN load after which nano hardness became stable while elastic moduli remained impervious to the change of indentation load. Furthermore, based upon electrochemical properties (i.e. Icorr, Ep, and Rp) samples welded at 1000 °C bonding temperature offered excellent corrosion resistance under 0.5M HCl environment.
