Özet

In this study, Al +% 10Al(2)O(3) composites produced by mechanical alloying (MA) method, transverse rupture strengths (TRS) includes determination of the characteristics. For this purpose, Al and Al2O3 powders was carried out to mechanical alloying process for 2, 4, 6, 8 and 10 hours. Size of the powder and SEM analyses of particles were done. Powders were pressed under 700 MPa pressure in one direction. The samples were sintered at 600 degrees C in flowing Ar atmosphere for one hour. Then, hardness, density, porosity and transverse rupture strengths (TRS) of sintered composites were determined. As a result of the experimental studies, it was determined that powder dimension was decreased with increased the duration of MA. It has also been determined that mechanical alloyed samples had lower density but also high hardness and TRS.
