This paper is an attempt to understand the characteristics of Al + TiO2 + Gr hybrid ball-milled composite powders, which would probably have extensive applications in the near future. Aluminum with titanium dioxide (TiO2) and graphite (Gr) powders was ball-milled in order to get a composition like: Al + 0% TiO2, Al + 5% TiO2, Al + 5% TiO2 + 2% Gr, Al + 5% TiO2 + 4% Gr and Al + 5% TiO2 + 6% Gr. The grain size, lattice space, lattice constant, stress, strain, dislocation density, and volume of the unit cell were calculated according to the data of X-Ray diffraction analysis of milled powders. Compressibility tests were performed in a hardened steel die under pressures between 100 to 500 MPa to determine Al with 5 wt.% TiO2 and 2 & 4 wt.% of Gr powder mixtures. For understanding the compaction behavior of aluminum-based hybrid composites reinforced with TiO2 and Gr particles under various applied pressure conditions, the experimental research was realized by using several powder compaction equations. The microstructure analysis is reported for the Al + 5% TiO2 + 6% Gr composite.
