Interaction between nano-precipitates and dislocations during high temperature deformation of Al-Si alloys
Source abstract
Abstract
Abstract The influence of nano-precipitates and dislocations on the static and dynamic recrystallization of the Al-Si based alloy modified with additions of Ti-V-Zr and deformed at 400 °C followed by annealing at 500 °C were studied by using electron backscatter diffraction and transmission electron microscopy. The dendritic morphology of the undeformed sample disappeared and grain coarsening with a serrated dislocation morphology were identified in the hot deformed and annealed sample. Rod-shaped nanosize and coherent (AlSi) 3 (TiVZr) precipitates were formed during T6 heat treatment, which changed to spherical shapes after annealing. The behavior of dislocations and precipitates which controlled the recrystallization is discussed.
