ABSTRACT:
Appropriately cleaned titanium or titanium alloy and iron-nickel alloy parts are bonded together to obtain a compound part by providing particular metallic layers in between them and diffusion welding the assembly together. The layer sequence is critical whereby vanadium is used always adjacent the titanium part and chromium or iron or nickel is used adjacent the iron-nickel part whereby chromium and iron can be directly bonded to the vanadium layer; in the case of nickel either chromium or tungsten and platinum are interposed.
