摘要：
Precipitation states in Cu-Li alloys produced by electrodeposition, employing strain amplitude dependent damping, ADD, measurements, have been 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 precipitates would be occurring. The evolution of ADD measurements and their influence on the modulus, along of the aging treatment were also determined.
