摘要：

A nanoscale characterization of neutron irradiated Oxide Dispersion Strengthened (ODS) alloys has been used to reveal the alpha-alpha' demixing and the population of (Y, Ti, O) nanoparticles. Multivariate statistical analysis (MSA) processed energy filtered transmission electron microscopy (EFTEM) efficiently reveals the location of all nanophases. The alpha-alpha' demixing did not only lead to the systematic formation of cube-on-cube semi-coherent Cr rich clusters but also to misfitting misoriented semi-coherent particles satisfying the orientation relationship [100](Cr)//[111](Fe) and [100](Cr)//[112](Fe). The misorientation angle between the semi-coherent directions < 110 >(Fe), and < 110 >(Cr) was found to be 17 degrees. (C) 2012 Elsevier B.V. All rights reserved.
