In this work, aluminum metal matrix composites (AMMCs) were fabricated by using powder metallurgy.
AA7075 powder is reinforced with two different ceramic particles (TiC,B4C) with different weight fractions (2.5, 5, 7.5 and 10 wt.%).
The composites were produced by powder metallurgy by preparing the powder, mixing, compacting and sintering.
The particle size of unreinforced AA7075 about 100μm, while particle size of each TiC and B4C about 150 μm.
The mixing process was done by planetary mixing setup rotating at 250 rpm for 2hr.
by adding zinc stearate as an activator material with steel ball milling.
However the mixture was compacted by hydraulic uniaxial press type (Leybold Harris No.36110) about 200 kg/cm² according to (ASTM-D 618).
After compacting process, the mixture sintered at 475 °C for 2hr.
by using electrical furnace with argon atmosphere.
There are many examinations and tests were carried out for the synthesized composites material (AA7075/ TiC and AA7075/ B4C) such as examination of the microstructure, mechanical tests such as hardness and compressive strength, physical tests such as density and porosity.
The results of this work showed that improving in physical properties (theoretical density, experimental density, porosity) and mechanical properties (Rockwell hardness and Compressive strength)
