Abstract
This paper reports for the first time the damping behavior of Mg-Al85Ti15 metastable composites synthesized using near dense blend-press-microwave sinter-hot extrusion methodology. Optical microscopy results show that the metastable particles were located along the grain boundaries and the formation of twins within the grains. In addition, scanning electron microscopy reveals reasonable distribution of particles, good matrix-particle interfacial bonding and minimal presence of microvoids. The damping test results show an increment in damping capacity and damping loss rate with the presence and increasing amount of particles. The effect of microstructure on damping characteristics of magnesium and damping mechanisms are discussed.
