Activation parameters of the Zener peak in Cu-Li alloys produced by electrodeposition

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 low and intermediate temperature grain boundary damping peaks of copper and also with the phase transition peak related to Cu-18 at% Li crystals. In this work the activation energy, H, and the pre-exponential factor τ 0 were calculated. Those were H = ( 160 ± 4 ) KJ/mol and τ o = 2 x 10 (-14 ± 1) (s).
