Titel
Submicroscopic and atomic scale structure changes during decomposition of Al alloys: a position annihilation study
Abstract
Positron annihilatation techniques are use to study the precipitation processes in quenched Al alloys of the type AlCu1.9, AlCu2.0Mg1.7 and AlSi1 at-%. From the experiments conclusions are drawn with respect to the structure and chemistry of nanometer-size precipitations which are responsible for the improved mechanical properties of these alloys.
