Abstract
Large-area electron beam (EB) irradiation method developed recently, the wide area on metal surface can be simultaneously smoothed due to high energy density of EB on the surface. However, if the workpiece has a hole shape, it is difficult to smooth the hole bottom surface, since the EB concentrates on the entrance edge or inside wall of the hole. In this study, expansion of smoothed area on the hole bottom surface was experimentally investigated by using a magnetic block with a through hole which is placed under the workpiece in large-area EB irradiation. Then, the influence of hole diameter and volume of the magnetic block on the smoothed area was discussed.
