Abstract: A new idea of using stiffer metallic reinforcement, such as titanium, in a ductile metallic matrix, such as aluminium, to enhance the dynamic properties (viz., stiffness and damping) is successfully attempted. The study focuses on the relationship between the stiffness and the damping capability of the aluminium matrix with the weight percentage of titanium added to it. Results of this study show that addition of about 3.2, 6 and 7.5 wt% of titanium increases the overall damping capacity of the Al matrix by 6, 17 and 24%, respectively. Particular emphasis is placed to rationalize the increase in damping in terms of the increase in dislocation density and presence of plastic zone at the matrix-particulate interface. © 2005 Springer Science + Business Media, Inc.
