Abstract

We demonstrate a means of extending the temperature range for structural applications of nanomaterials through introduction of a dispersion of precipitates, whose thermal stability determines the temperature at which strength deteriorates. Precipitate-stabilized nanostructures created via severe plastic deformation of Inconel are shown to be stable even after heat treatment for 240 h at temperatures up to one-half of the melting point. This stability results from retention of both the fine microstructure and precipitate phases at high temperatures. (C) 2007 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
