Abstract
AbstractPositron annihilation, as a well‐established experimental tool in the materials science community, provides unique information about the behavior of the material microstructure after radiation treatment. The experimental simulation of radiation damage by charged particle implantation is, as a first approach, a very reasonable way to study radiation embrittlement. The article presented by Vladimir Kršjak et al. on p. 2339 ff. discusses this timely topic on recent experiments on helium implanted Fe–Cr model alloys. Simultaneous results from positron beam and conventional depth profiled positron lifetime techniques are demonstrated. In the cover picture, the intensity of the positron lifetime component I3 characterizes the presence of large open volume defects (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
