Copper-lithium alloys were produced by electrodeposition. They show a Zener peak at 650 K (at 0.2 s-') which appears overlapped with the low and intermediate temperature grain boundary damping @s of copper and also with the phase transition peak related to Cu-18 a% Li crystals. In this work the activation energy, H, and the pre-exponential factor 70 were calculated. Those were H = ( 160 * 4 ) KJ/mol and 70 = 2 x 10 (-I4 * (s).
