Abstract
2219 aluminum alloy reinforced with 10wt. % TiB2 particulate was fabricated through mixed-salts method. The damping capacity and dynamic Yongs modulus was investigated. The damping capacity and dynamic Yongs modulus of 10wt. % TiB2/2219 is higher than that of the matrix alloy.The improved damping capacity is due to dislocation damping at low temperature, and grain boundary damping and interface damping at high temperature.
