摘要：
Zinc bicrystals with 89degrees <10 (1) over bar0> symmetric tilt boundary inclined at different angles to the free surfaces are annealed in the field of 17 T. Boundaries migrate reorienting almost perpendicular to the surfaces. The observed effect is due to combination of magnetically induced and capillarity driven boundary migration. The absolute boundary mobility was measured to be about 2.5 x 10(-8) m(4)/Js. (C) 2002 Acta Materialia Inc. Published by Elsevier Science Ltd. All rights reserved.
