Aluminum Alloys Reinforced by Nano-Particles Dispersion
Abstract
The synthesis and mechanical-microstructural characterization on nanocomposites was the focus in this project. Nanoparticles of different nature (C and silver nanoparticles) and nanofiber (carbon nanotubes) were used as reinforcement phase. In the beginning pure aluminum matrix was employed to produce nanocomposites, at the end was explored the possibility to scale this results to aluminum alloys (AA2024 and AA7075). Nanoparticles (NPs) dispersion showed an increment in mechanical properties as a function of the NP content. Graphite NPs favor the formation of an apparent aluminum oxi-carbide with amorphous structure. Silver nano particles (AGC-NP) kept the morphology after all experimental process: this means that AGC-NP were not dissolved or deformed during processes. In the same case to graphite NP. when AGC-NP were used as reinforcing phase, an increment in mechanical properties was observed as a function of AGC-NP content. There are several strengthening mechanisms working in these nanocomposites. Some of them are commented and discussed in published articles.
