Deformation of zirconium irradiated by 4.4 MeV protons at 347 K

摘要

Proton irradiation tests have been performed on two cold-worked zirconium specimens using 4.4 MeV protons with controlled displacement damage rates between 1.4 and 6.9 x 10(-7) dpa s(-1). The specimens had different Fe contents, nominally pure (NP): 64-70 ppm by weight, and ultra-high purity (UP): 3-5 ppm by weight. A stress of 50 MPa was applied during the tests, and the test temperature was 347 K. Crown Copyright (C) 2004 Published by Elsevier B.V. All rights reserved.
