SELF-DIFFUSION IN MOLYBDENUM
The radioactive isotope Mo/sup 9/ was used to study selfdiffusion in polycrystalline and single crystal specimens of molybdenum in the temperature range 1850 to 2350 deg C. Diffusion zone analysis was carried out by serial sectioning with a lathe and gamma -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).
