Abstract

© The Society for Experimental Mechanics, Inc. 2017. In this work, scrap Aluminium Matrix Composites (AMCs) reinforced with 10 wt% nano iron oxide (Fe3O4) were produced and the influence of doping Fe3O4 with TiO2 at 2.5 %, 5 %, 7.5 % and 10 % wt%, was studied. For the dispersion of the reinforcement and the study of the matrix/reinforcement, interface was evaluated by Scanning Electron Microscopy (SEM). Density and microhardness of the composites were measured and compared. Wear and creep response of the composites were evaluated by a nanoindenter, Furthermore modulus and hardness of the composites were calculated using the unloading data from the nanoindentation tests. Relatively homogenous distribution of the constituents, with a good bond between matrix and the reinforcements was observed. It was also observed that wear behaviour improved with the increase in the TiO2 content.
