Abstract

We report herein, for the first time, the effects of high-fluence (2 × 1017 ions cm-2; 14 at.%) helium irradiation of polycrystalline Ti3AlC2 samples at 500°C. X-ray diffraction (XRD) confirmed that, despite swelling along the c-axis and shrinkage along the a-axis, the basic building blocks, viz. the Ti 3C2 layers, remained intact after irradiation. The XRD results also suggest that He implantation disorders the Al layers. Despite the high dose at 500°C, He bubbles are present and are less than 1 nm in diameter. This is an important finding if this material is to be used in light water or other fission reactors in the future. © 2014 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
