ABSTRACT
The effectiveness of using a barrier layer of vanadium in a bimetallic composition consists of stainless steel 08Cr18Ni10T + vanadium VnPd-1 + titanium VT1-0 obtained by explosion welding meant to prevent the formation of an intermetallic interlayer under the effect of different temperatures was investigated. The evolution of the near-weld zone was investigated by analysis with scanning electron microscope of microsections from samples heated at 600, 700, 800 and 900 °C with 1, 3, 5 and 10 hours exposures. The researches indicated that the barrier layer of vanadium reliably prevents mutual diffusion between steel and titanium at high temperatures, thus eliminating the formation of intermetallic compounds in the adjacent zone. The limit of the barrier layer effectiveness was determined.
