Abstract
Precipitation states in Cu-Li alloys produced by electrodeposition, em ploying strain amplitude dependent damping, ADD, measurements, have be en determined. A hardening of the sample during the two precipitation ranges from room temperature up to 375 K and from 550 up to 675 K, has been found. Meanwhile a softening of the sample was found between 375 up to 525 K and 675 up to 800 K, where the dissolution of precipitate s would be occurring. The evolution of ADD measurements and their infl uence on the modulus, along of the aging treatment were also determine d.
