| Popis: | The efficiency of using a vanadium barrier layer and a bimetallic composition composed of 08Kh18N10T stainless steel + VT1-0 titanium obtained by means of explosion welding in order to prevent occurrence of an intermetallic layer is studied in different temperature ranges. The evolution of the heat-affected zone in the samples subjected to heating to 600, 700, 800, and 900°C with exposure times of 1, 3, 5, and 10 h is studied with the use of scanning electron microscopy and metallography, and also the microhardness is measured. It is shown that the vanadium barrier layer reliably prevents mutual diffusion between steel and titanium at a high temperature, which excludes the formation of intermetallic compounds in the heat-affected zone. The efficiency of the barrier layer is evaluated. |
