Abstract
In this study, we tried to make hybrid aluminum metal matrix composites (AMMCs) reinforced by adding steel slag and Gr particles in it by combined powder metallurgy and press bonding process with 15% of blast-furnace slag and variable values of Gr contents. By examining the composite microstructure, the excellent distribution of particles in matrix aluminum as well as accuracy in the results, no reaction is observed between Al and particles. The obtained results showed that the wear rate and density of hybrid composite samples decreased to 2.3% and 24% by increasing the Gr volume contents, respectively. Also, the wear rate of samples which is related to the hardness value, increased by 181% by increasing the Gr content up to 10[Formula: see text]vol.%.
