研究了原位Al/TiB 2复合材料和Ti过量复合材料的阻尼性能。该复合材料是通过K2 TiF 4和KBF 4盐的放热反应过程制备的。使用动态机械热分析仪研究了材料在30-300°C温度范围内的阻尼行为。实验结果表明，当温度低于110°C时，Ti过量复合材料的阻尼性能低于Al/5wt%复合材料，而当温度高于110°C时，Ti过量复合材料的阻尼性能高于Al/5wt%复合材料。Ti的主要作用是在TiB 2颗粒表面形成薄层，从而改变了材料的阻尼性能。
The damping capacity of in situ aluminium (Al)/TiB2composite and composite with Ti excess was investigated. The composites were fabricated with an exothermic reaction process via K2TiF4and KBF4salts. 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/5wt% composite when temperature below 110°C and higher than of Al/5wt% composite above 110°C. The main effect of Ti is the formation of thin layer on TiB2particulates resulted in the change of damping capacity.
