Study on damping behavior of FeAl3 reinforced commercial purity aluminum
AbstractCommercial purity aluminum composites with 5wt% of FeAl3 reinforcement were investigated. Samples of dimension 50×3.5×3.5mm for damping measures were obtained by spark machining. The damping behavior of FeAl3 reinforced composites and base alloy was studied over a temperature range of 30–300°C using a dynamic mechanical thermal analyzer. The Al/FeAl3 composites were found to exhibit higher damping capacity compared to Al matrix. The damping mechanisms associated with Al/FeAl3 composites were ascribed to dislocation damping at low testing temperatures, and to dislocation damping, and interface damping at high testing temperatures.
