Effect of Ti on the damping behavior of aluminum composite reinforced with in situ TiB2 particulate

Damping capacity of in situ Al/TiB2 composite and composite with Ti addition was investigated. The composites were fabricated with an exothermic reaction process via K2TiF4 and KBF4 salts. Experimental results indicate that existence of Ti alters the TiB2/aluminum interface, resulting in a change in damping of the Al/TiB2 composite.
