Study of Recovery Stages in 2024 and 7075 Aircraft Materials Plastically Deformed by Using Nuclear and Electrical Techniques

Positron annihilation and electrical measurements have been performed to study the isochronal annealing of wrought 2024 and 7075 aluminum alloys in a temperature range from RT to 773 K after being deformed at RT with 25% deformation. Two annealing stages of microstructures were distinguished which w...

Zusammenfassung:	Positron annihilation and electrical measurements have been performed to study the isochronal annealing of wrought 2024 and 7075 aluminum alloys in a temperature range from RT to 773 K after being deformed at RT with 25% deformation. Two annealing stages of microstructures were distinguished which were attributed to recovery in 2024 due to point and dislocations respectively and only one due to dislocations in 7075.
