Abstract

Internal friction is reflecting a conversion of mechanical energy to heat and causes attenuation of vibrations in the material. This article is aimed at the effect of precipitation hardening on the hardness of AZ 61 magnesium alloy. The changes of microstructure were mapped by internal friction with use of the ultrasonic resonance device. The goal was to find the relationship between the internal friction and microstructure of the experimental material.

Keywords:
