The Impact

The impact of a magnetic field on texture and microstructure evolution in Zn-1.1%Al was investigated. Specifically oriented cold rolled (85%) sheet specimens were annealed in a magnetic field of 17 Tesla at 340°C for 15, 30 and 90 minutes. X-ray diffraction and EBSD-measurements were utilized to characterize crystallographic texture and grain microstructure. The results confirmed that grain growth in magnetically anisotropic zinc can be substantially affected by a magnetic field. This manifested itself by significant changes in the development of the grain growth texture during magnetic annealing compared to annealing at zero field. The magnetically induced texture changes are caused by the generation of an additional magnetic driving force which arises from a difference in magnetic free energy density between differently oriented grains. The grain microstructure evolution was also essentially affected by a magnetic field such that grains with energetically favoured orientations grow faster and their fraction becomes larger, than that of grains with disfavoured orientations. The results will be also discussed with respect to the magnetically altered grain boundary character distribution.
