摘要：
As-homogenized beta-phase Mg-14.3Li-0.8Zn (LZ141) alloy exhibits a P-1 peak and a conspicuous high-temperature damping background (HTDB) in the heating internal friction Q(-1) curves. Cold-rolled LZ141 alloy with 80% thickness reduction exhibits a significant P-2 peak in the Q(-1) curves due to the recrystallization process during heating. The activation energy (H) of the HTDB for as-homogenized LZ141 alloy is 1.44 eV, decreasing to 0.91 eV after 80% cold-rolling. These H values for beta-phase LZ141 alloy are lower than those for a-phase AZ80 alloy. Cold-rolled LZ141 alloy exhibits extremely high damping capacity at temperatures around the P-2 peak.
