Ag-rich precipitates formation in the Cu-11%Al-10%Mn-3%Ag alloy
MetadataShow full item record
The formation of Ag-rich precipitates in the Cu-11%Al-10%Mn-3%Ag alloy initially quenched from 1123 K was analyzed. The results showed that nanoprecipitates of a Cu-rich phase are produced at about 523 K. In higher temperatures these nanoparticles grow and the relative fraction of Ag dissolved in it is increased, thus forming the Ag-rich phase. (C) 2013 Elsevier B.V. All rights reserved.
