Characterization of Diffusion Welded Joints between Titanium and Permendur Type Alloy Using Different Interlayers

The experiments regarding the solid–state diffusion bonded joints prepared between commercialy pure titanium and permendur type soft magnetic alloy are presented. The diffusion bonding of these materials were carried out using copper and nickel interlayers, in the temperature range of 850-950 C for 1,5 hrs., under uniaxial pressure, in argon atmosphere. The microstructure of the transition joints were revealed by optical microscopy and the presence of different intermetallic compounds at the interface were examined by X-ray diffraction. The technological parameters which led to good jonctions for the studied systems were also specified.
