Mass-transport in W-Cu system under high energy electron irradiation

The research of the mass-transport effect was conducted for the system “W-Cu”, the components of which were non-dissolved both in the solid and in the liquid conditions. It has been shown that under the electron irradiation the mutual solution copper and tungsten took place on the passing zone and reaches 30% for both tungsten and copper. The depth of the mutual penetration was 8–10 mm. The possible mechanisms of this effect are dissussed.
