Abstract
The radioactive isotope 99Mo has been used to study self-diffusion in polycrystalline and single crystal specimens of molybdenum in the temperature range 1850 to 2350°c. Diffusion zone analysis was carried out by serial sectioning with a lathe and γ-ray activity measurements with a scintillation counter. The two kinds of specimen gave similar results, diffusion coefficients in the polycrystalline material are expressed by D=0•5 exp(-96•9/RT), and in the single crystals by D=0•1 exp (—92•2/RT).Keywords
