Abstract
Rapidly solidified Al-Y-Ni-Co-Pd alloys contain highly dispersed primary α-Al nanoparticles of about 5 nm in size homogeneously embedded in the glassy matrix with an extremely high density of precipitates of the order of 1024 m-3. These particles grow at the temperature below a glass-transition temperature. The first direct observation of micro-strain regions and dislocations quenched in nanoparticles with a size about 5 nm is provided.
