Internal friction peak associated with dislocations in Mg-0.6%Zr alloy

The internal friction （IF） of Mg-0.6%Zr alloy is measured in the present study and two IF peaks of （PI （97 ℃, 1 Hz） and P2 （230 ℃, 1Hz）） are found, respectively. It is shown that the novel P1 peak is frequency independent and the peak temperature increased with the increase of strain amplitude or he...
