Energy-Filtered imaging of Cu-nanoprecipitates

Conference item

Abstract:: Energy-Filtered (EF) TEM imaging has been used to reveal and measure the size of individual Cu-precipitates as small as 2nm embedded in ferritic steels. Optimisation of the acquisition and analysis procedures is described. A procedure was developed to identify the contributions to spatial resolution limit from fundamental factors, drift and instrument instabilities. A long data acquisition time is necessary during which drift occurs that ultimately limits detection. Nevertheless, EFTEM provides a viable method for revealing the precipitation.
