Abstract:
In this study, Al matrix composites consisting of different amounts of Zn,
Cu, and Mg were produced using the powder metallurgy technique. In the
alloying, powders were ball milled for 120 min via mechanical alloying.
After alloying process, the powders were pressed at 800 MPa at room
temperature. Sintering (2 h at 600?C in argon atmosphere), solution
treatment (2 h at 480?C), and aging processes (3, 6, 9, and 12 h,
respectively, at 120?C) were applied to the samples. The hardness and
tribo-metallurgy properties of the products were investigated. After
sintering, the hardness values of the three alloys were close to each other;
however, the solution treatment after sintering caused the hardness values
to increase significantly. It was determined that the Al-2Zn-5Cu-4Mg alloy
had the highest hardness increase with the 6-h aging heat treatment. The
wear resistance of the materials in all the compositions had increased. The
highest wear resistance and lowest friction coefficient were obtained for
the Al-2Zn-5Cu-4Mg alloy with the 6-h aging heat treatment.
