Abstract

Self-diffusion in single-crystal tungsten and diffusion of rhenium tracer in single-crystal tungsten have been measured over the temperature range 2660 C to 3230 C by the direct sectioning technique. The initial radioactive layer of tungsten and rhenium tracers was produced on the diffusion samples by bombardment with 9. 0-MeV deutrons. It was shown that the initial radioactive layer satisfactorily approximated the boundary-condition requirements of the one-dimensional diffusion equation. The tracers observed in determining the diffusion coefficients were W^185, Re^183, and Re^184.
