Abstract

The effects of an inhomogeneous distribution of second-phase particles on nucleation of recrystallization in a particle-containing aluminum alloy are investigated by 3-D serial sectioning. Clusters and bands of big intermetallic particles are the dominating nucleation sites, but other sites are also active. The effects of nucleation sites and the inhomogeneous particle distribution on the orientation and size of the nuclei are investigated and their relationships are discussed.
