Abstract
Magnetically driven migration of planar 〈101¯0〉 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 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 and 2.15 eV.
