Abstract Scope |
Metal matrix nanocomposites (MMNCs) are studied as a means to reduce overall product weight in automotive and aerospace industries while improving mechanical properties such as tensile strength and wear resistance for both ambient and elevated temperatures as compared with monolithic alloys. In-situ methods for producing MMNCs offer enhanced matrix-particle bonding, particle size distribution, and reduction in contamination and potentially cost and complexity as compared with ex-situ processes and are thus preferred for future MMNC production. This research focuses on the processing parameters and microstructural evolution for aluminum nanocomposites made via metal-based pyrolysis (MBP). The MBP process occurs by pyrolyzing an organic precursor polymer within a melt, whereby the metal acts as a pseudo-inert environment. As the polymer breaks down the elements within its chain are used to create ceramic nanoparticles, thus forming an MMNC. The effect of varying precursor composition on nanoparticle formation will be presented. |
