Popis: The damping capacity of in situ aluminium (Al)/TiB2 composite and composite with Ti excess was investigated. The composites were fabricated with an exothermic reaction process via K2TiF4 and KBF4 salts. The damping behavior of materials over a temperature range of 30–300 °C was investigated using a dynamic mechanical thermal analyzer. Experimental findings indicate that damping capacity of composite with Ti excess is lower than that of Al/5 wt% composite when temperature below 110 °C and higher than of Al/5 wt% composite above 110 °C. The main effect of Ti is the formation of thin layer on TiB2 particulates resulted in the change of damping capacity.
