Analyzing the misorientations of nanoblocks formed in FCC metals under ion irradiation

Abstract

The results from studying the nanostructural states formed upon ion irradiation in subsurface volumes of pure metals (Pt) are presented. The formation of a nanocrystalline structure with block sizes of 1-5 nm are observed at a distance of no less than 20 nm from the irradiated surface. It is shown that block boundaries have low-angle misorientations of less than 6° ± 2°. © 2012 Allerton Press, Inc.
