The present study evaluated hardness, tensile properties and two-body abrasive wear behaviour of Al–Mg–Si alloy specimensartificially aged at 448 K for different durations ranging from 0.5 to 504 h. In addition to the measurements of Vickers hardnessand tensile properties, wear tests of differently aged alloys were conducted against SiC abrasive paper of 220 grit sizeunder normal load of 9.81 N with the help of a pin-on-disc tribometer. Abrasive wear characteristics were assessed in termsof measurements of specific wear rate and roughness of the abraded surfaces. These were substantiated via examinations ofworn surfaces, collected wear debris and subsurfaces of worn specimens to comprehend the micro-mechanisms of abrasion. The abrasive wear performance varied significantly with the duration of artificial aging and the lowest specific wear rate aswell as roughness of the abraded surfaces corresponded to the peak-aged condition. An attempt was also made to correlatemechanical properties and tribological performance. It was found that the specific wear rate exhibited direct linear relationwith the strain hardening exponent, and inverse linear relationships with hardness, yield strength and strength coefficient. Microplowing, microcutting and microcracking were identified as mechanisms of abrasion; the extents of these processeswere found to be governed by the state of aging that determined the mechanical properties.
