A study of damping capacities in pure Mg and Mg-Ni alloys

Excellent damping capacities were observed in pure Mg and hypoeutectic Mg-Ni alloys. Two damping peaks (P1, P2) were found at 100 °C and 230 °C, respectively. P1 was a newly detected damping peak, which was considered to derive from the movement of dislocations; it has great significance for practical applications.
