Magnetically driven migration of specific planar grain boundaries in Zn bicrystals

C Guenster et al

Magnetically driven migration of planar View the MathML source tilt grain boundaries with various misorientations in high purity zinc bicrystals was measured in-situ by means of a specially designed polarization microscopy probe. The absolute grain boundary mobility and its temperature dependence were measured in the regime between 330°C and 415°C. The results revealed that there is a pronounced misorientation dependence of grain boundary mobility in the investigated angular range. The migration activation enthalpy was found to vary between 1.18 eV and 2.15 eV.
