Abstract

Attenuation of acoustics waves and Grüneisen parameter has been investigated in AMG-2 and SAV-1 aluminum alloys used as a construction material in nuclear reactors. The measurements of attenuation coefficient of longitudinal acoustics waves were carried out by the echo pulse method at frequencies 10 and 30 MHz and temperature range 290 – 580 K. The maximum observed in temperature dependence of attenuation coefficient is explained by different relaxation mechanisms
