Abstract

The B-H hysteresis loop and Barkhausen noise have been measured in the neutron irradiated SA508 steel of 45 μm thickness. The coercive force of B-H loop showed a slow change up to a neutron dose of 10¹⁴ n/cm² and increased by 15.4% for a 10¹⁶ n/cm² dose sample compared with that of the unirradiated one, related to the domain wall motion hindered by the increased defects. However, the amplitude of Barkhausen noise reflecting the wall motion decreased slowly up to 10¹⁴ a/cm² irradiation, followed by a rapid decrease of 37.5% at 10¹⁶ n/cm².
