Change of internal friction on aluminium alloy EN AC 51200 depending on temperature
Journal Title: Production Engineering Archives - Year 2015, Vol 0, Issue 1
Abstract
The article is focused on the analysis of changes in the dependence on temperature on the aluminium alloy EN AC 51200 (10,1% Mg, 1,32% Si and 0,43% Mn) by internal friction. Internal friction is a property of the material measured on the ultrasonic resonant apparatus at a frequency of about f = 20470 Hz. The measured temperature range was from 50 °C up to 420 °C. The precise measurement of the inter-nal friction can be monitored on an ongoing process by structural changes and various mechanisms that prevent these changes.
