Influence of Particulate Reinforcements on the Damping Behavior of Magnesium

The properties of magnesium, specifically the specific stiffness, strength and damping, can be enhanced by the addition of reinforcements such as silicon carbide particulates. This paper highlights the results of a study aimed at investigating the possible variation in overall damping property, measured using an impact based vibration method coupled with circle‐fit approach, which focuses on the internal friction arising at the matrix‐reinforcement particulate interfaces. The study also examines the intrinsic influence of a second reinforcing phase, which is particulate of titanium, along with particulates of silicon carbide.
