milled composite powders, which is anticipated to have large application in the near future.
Aluminium with titanium dioxide (TiO₂) and graphite (Gr) powders was ball milled in
order to yield the composition like: Al + 0% TiO₂, Al + 5% TiO₂, Al + 5% TiO₂ + 2% Gr,
Al + 5% TiO₂ + 4% Gr and Al + 5% TiO₂ + 6% Gr. From the X-Ray diffraction analysis
of the milled powders, the grain size, lattice space, lattice constant, stress, strain, dislocation
density and unit cell volume were calculated. Compressibility was performed in a
hardened steel die at pressures between 100 to 500 MPa to determine Al with 5 wt.% TiO₂
and 2 & 4 wt.% of Gr powder mixtures. For understanding of compaction behavior of aluminum
based hybrid composites reinforced with TiO₂ and Gr particles under various
applied pressure conditions, experimental research has been made using several powder
compaction equations. Microstructure analysis for Al + 5% TiO₂ + 6% Gr composite has
been reported. |
