AbstractThis research studied the effect of the Heat Treatment on the Mechanical Properties and the Wear Rate of the pure Aluminum with a particle size of (≤53μm). The Aluminum is reinforced by graphite with a particle size of (≤63μm) with an addition of glass particles with different weight ratios of (3, 6, 9, and 12) Wt. % and a particle size was (≤ 53μm).
Powder metallurgy technique has been used to manufactured the samples, where the samples are pressed uniaxial at room temperature with (500 Map), then sintering at (550 C0) for (2 hr.). After that, heat treatment is applied on the samples at (500 OC) for one hour and Quenched in water.
There was a great improvement of the mechanical properties such as the hardens and the compressive strength. This improvement was proportional with the Weight ratio of the glass particles before and after the Heat Treatment.
On the other hand, there was a decrease of the wear rate versus the increase of the Weight ratio of the glass particles and heat treatment.
