The characteristic of damping peak in Mg–9Al–Si Alloys
چکیده انگلیسی

The damping capacity of as cast Mg–9Al–Si alloys was investigated. A damping peak exhibits at around 420 K for a frequency of about 1 Hz and it was correlated to the characteristic grain boundary peak of magnesium. The activation energy of damping peak is lower than self-diffusion activation energy of pure magnesium, but higher than activation energy of AZ91 reported. The effect of measurement conditions including strain amplitude, heating rate and consecutive measurement number on damping peaks has also been discussed.
