摘要：

The magnetically driven motion of planar symmetrical and asymmetrical <10<(1)over bar>0> tilt gram boundaries in high purity (99,995%) zinc bicrystals was measured in-situ by means of a polarization microscopy probe in the temperature range between 330 degrees C and 415 degrees C and the corresponding migration activation parameters were obtained. The results revealed that grain boundary mobility essentially depends on the misorientation angle and the inclination of the boundary plane. The magnetic annealing of the cold rolled (90%) Zn-1.1%Al sheet specimens resulted in an asymmetry of the two major texture components. This effect is attributed to a magnetic driving force for grain growth. The grain microstructure evolution was also essentially affected by a magnetic field.
