The extensive experimental work on age hardening of Al- and Mg-based alloys, performed by the associated groups at IFIMAT (UNCentro, Argentina) and at LNESS (Politecnico di Milano, Italy) in recent years, is discussed here in a comprehensive way, with attention to experimental procedures and to results of general validity. For Al-based alloys, the established knowledge regarding the different action of Zn, Cu, Mg and Ag in the formation of vacancy-solute clusters is presented. For Mg-based alloys, the limits of positron annihilation spectroscopy are discussed on the basis of experience in progress.

Abstract
The extensive experimental work on age hardening of Al- and Mg-based alloys, performed by the associated groups at IFIMAT (UNCentro, Argentina) and at LNESS (Politecnico di Milano, Italy) in recent years, is discussed here in a comprehensive way, with attention to experimental procedures and to results of general validity. For Al-based alloys, the established knowledge regarding the different action of Zn, Cu, Mg and Ag in the formation of vacancy-solute clusters is presented. For Mg-based alloys, the limits of positron annihilation spectroscopy are discussed on the basis of experience in progress.File in questo prodotto:
