Abstract

Measurements of solute GB diffusion in Cu and Ag polycrystals were carried out in Harrisons type-B and type-C kinetic regime using 75Se, 195Au, 63Ni radioisotopes. In the B-regime at high temperatures, the GB diffusion parameter sδDGB was determined (s being the GB segregation factor, δ the GB width and DGB the GB diffusion coefficient), while in the C-regime at low temperatures DGB values were measured directly. The investigations of these differently behaving solute–solvent systems on Cu and Ag basis yield information on solute GB diffusion and segregation in relation to solute–solvent atomic binding and solute–vacancy interaction in the bulk and in GBs. The GB diffusion of 64Cu and 195Au in a series of near ∑ = 5, Θ = 36.9° (310) [001] Cu tilt GBs and of 71Ge in a series of near ∑ = 7, Θ = 38.2° (123) [111] Al tilt GBs in dependence on the tilt angle Θ and on the temperature was studied. A characteristic minimum in the GB diffusion parameter and a maximum in the activation energy was observed at the ideal CSL GBs.
