Abstract
Copper-lithium alloys were produced by electrodeposition. They show a Zener peak at 650 K (at 0.2 s(-1)) which appears overlapped with the l ow and intermediate temperature grain boundary damping peaks of copper and also with the phase transition peak related to Cu-18 at% Li cryst als. In this work the activation energy, H, and the pre-exponential fa ctor tau(0) were calculated. Those were H = (160 +/- 4) KJ/mol and tau (0) = 2 x 10((-14 +/- 1)) (s).
