Ackland %J Physics %D 2013 %I arXiv %X An extensive set of first-principles density functional theory calculations have been performed to study the behaviour of He, C and N solutes in austenite, dilute Fe-Cr-Ni austenitic alloys and Ni in order to investigate their influence on the microstructural evolution of austenitic steel alloys under irradiation. %U http://arxiv.org/abs/1301.5317v1
