Interfacial properties of diffusion bonded Ti-6Al-4V to AISI 304 stainless steel by inserting a Cu interlayer

Effect of a copper filler metal on the microstructure and mechanical properties of electron beam welded titanium–stainless steel joint

“…They cited large internal stress induced by differences in linear expansion and thermal conductivity between titanium and steel. Currently, indirect joining is generally realized by adding an intermediate metal layer such as Ni, Al, Ag, or Cu to prevent atomic diffusion between Ti and Fe, Cr or Ni [9][10][11][12][13]. Among the interlayer metals mentioned above, copper is more frequently used.…”

Characterization of diffusion-bonded titanium alloy and 304 stainless steel with Ag as an interlayer

“…Maximum shear strength of 118 MPa was obtained in a sample bonded at 870°C, bonding pressure of 1 MPa, and holding time of 90 min due to better diffusion of mating surfaces. The increase in the shear strength may be attributed to high diffusion rate of copper into Ti alloy under the conditions specified by Ozdemier et al [10].…”

“…Earlier studies [10] done with the Ti alloy and stainless steel with copper interlayer diffusion-bonded at 1-MPa pressure produced a bonding strength of 118 MPa. In the current investigation with silver as interlayer, higher shear strength of 158 MPa is obtained at a pressure of 5 MPa as shown in Fig.…”

“…Previous work on the interfacial properties of diffusionbonded Ti-6Al-4 V to AISI 304 stainless steel with Cu interlayer done by Ozdemir et al [10] revealed the following. Bonding was carried out at temperatures of 830, 850, and 870°C for holding times of 50, 70, and 90 min, respectively, under 1-MPa load in an argon atmosphere.…”

A fractal model of normal dynamic parameters for fixed oily porous media joint interface in machine tools

“…In reference [4], Bartosz Powałka and Tomasz Okulik presented a new technology for the assembly of ball guideway systems which involve the use of a thin layer of a casting compound to suppress vibration and chatter in machine tools. Since 40-60 % of the total dynamic stiffness and about 90 % of the total damping in a whole machine tool structure originate in joint interfaces [5][6][7][8], it is beneficial to design and build high stiffness and damping joint interface for the mechanical properties of an integrated machine tool to improve the cutting machining accuracy.…”
