Abstract: In order to develop a high damping aluminum alloy with strength, in-situ A356/TiB2 composite fabricated with an exothermic reaction process via K2TiF4 and KBF4 salts were studied. The damping behavior of materials over a temperature range of 30300℃ was investigated using a dynamic mechanical thermal analyzer. Experimental findings indicate that damping capacity of A356/TiB2 composite is higher than that of A356 base alloy. Damping capacity of materials increases with increasing temperature while decreases with increasing frequency. Interestingly, the improvement of both damping capacity and tensile strength is observed simultaneously.
