“…The 444A and 439 ferritic stainless steels had titanium nitrides and the 304A austenitic stainless steel, chromium nitrides, in accordance with the literature 13,16 . Figure 6 shows secondary electron images (SEM) and the collected spectra (EDS) confirming the chemical composition of these inclusions.…”

“…It is observed that the 1010, 439, 444A and 410D steels, have predominantly ferritic microstructure, as expected [8][9][10][11][12][13][14][15][16] . However, there is a significant difference in the morphology …”

“…The 304A stainless steel has a good ductility, good resistance to stress-corrosion in environments containing chloride, good resistance to pitting corrosion and is hardenable by mechanical forming [13][14][15][16][17] . As there are no international standards accepted for mechanical tests on extended sheets, this work has a original character, regarding the experimental methodology and the fact that it presents the possibility of materials substitution in extended sheet manufacturing.…”

“…The observed trend of variation in hardness in the present study is in line with the nanoindentation studies available in the literature pertaining to diffusion bonding of Ti alloys to steels. [34,[36][37][38][39] Furthermore, the hardness results are also comparable to the reported microhardness values at the interfaces of Ti/SS diffusion-bonded joints. [12,14] D. Shear Behavior of the Ti64/IF Steel Joints The shear test curves indicate that some of the joints behaved in a brittle manner with limited shear ductility and reduced shear strengths, whereas the other joints exhibited noticeable shear ductility and improved shear strengths.…”

The application of interlayers in solid-state diffusion bonding is considered for facilitating improved joint strength as well as optimizing the bonding parameters. In case of dissimilar metals, the interlayers are preferred to promote diffusivity by reducing the metallurgical incompatibility. In the present work, the effect of formation of intermetallics at interfaces of the dissimilar joints between Ti-6Al-4V (Ti64) alloy and interstitial free (IF) steel, produced by direct diffusion bonding as well as by using the interlayers of copper and nickel, was evaluated. The diffusion bonding experiments were performed in a temperature range of 1023 K to 1223 K, under a constant pressure of 10 MPa for 10 minutes, in high vacuum conditions. It was observed that diffusion of interlayer(s) into the base metals increased with bonding temperature, which led to the increase in intermetallic layers at the joint interface. At 1223 K, the influence of interlayer on microstructure of interfaces was reduced by complete diffusion of interlayers and subsequently led to the interdiffusion of base metals. The maximum shear strength of~186 MPa was recorded for the bonding performed using a nickel interlayer at 1023 K. Detailed microstructure analysis, nanoindentation measurements and shear tests suggest that the presence of a thin layer of hard TiFe intermetallic at the interface has no adverse effect, but a soft remnant interlayer can deteriorate the shear properties of the diffusion-bonded joints.
