PT Journal AU Uhricik, M Palcek, P Soviarova, A Snopinski, P TI Change of Internal Friction on Aluminium Alloy with 10.1 % Mg Dependence on the Temperature SO Manufacturing Technology Journal PY 2014 BP 467 EP 470 VL 14 IS 3 DI 10.21062/ujep/x.2014/a/1213-2489/MT/14/3/467 DE Internal Friction; Aluminium Alloy; Resonant Frequency; Temperature AB The article is focused on the analysis changes dependence on the temperature on the aluminium alloy with 10.1% Mg, 1.32% Si and 0.43% Mn by internal friction. Internal friction is a property of the material is measured on the ultrasonic resonant aparature at a frequency about f = 20470 Hz. The measured temperature range was from 50 °C up to 420 °C. Precisely measurement of the internal friction can be monitored ongoing structural changes and various mechanisms that prevent these changes. ER
