Abstract
Grain boundary particles of a ternary, a Mn- containing and a Zr-containing Al-Zn-Mg alloys have been investigated. In the Mn-containing alloy, dispersoids are encountered the grains as well as at the grain boundaries (GBs) together with the equilibrium eta-phase. Large Mn-bearing particles are also present at the grain boundaries in this alloy, however they do not pin the GBs as the Zr-bearing particles. The distribution of the Zr-bearing dispersoids is observed to be irregular both in the grain itself and at the grain boundaries. These effectively impede grain growth.
