Wear performance investigation of AlSi8Cu3Fe aluminum alloy related to aging parameters

Aluminum silicon alloys are the most preferred alloys for industrial applications due to their ease of production and lightness. It is important to improve the mechanical properties of these materials in order to increase their usage. Wear properties are one of these mechanical properties that can be improved. In this present investigation, 3 different artificial aging durations; 2 hrs, 4 hrs, 8 hrs aging at 200 °C were applied after solution heat treatment for 4 hrs at 540 °C to the AlSi₈Cu₃Fe alloy. Microstructural analysis and mechanical tests were applied to understand the effect of aging parameters on wear performance and also hardness values of AlSi₈Cu₃Fe alloy. According to the results obtained from tests and analyses, the highest wear resistance was reached on the 4 hrs aged sample.
