“…[7][8][9] An ideal route to improve the mechanical properties of Al-Mg-Si alloys is to expose them to ageing treatments for the precipitation of intermetallics from the solute atoms within the matrix of the alloy. [7] The influence of ageing treatment on the mechanical properties, [10][11][12][13] fatigue [14][15][16][17] and tribological behavior [18,19] were extensively studied for this kind of alloys in the past. Some of these reports have suggested that the change in the precipitation state predominantly influences the investigated properties.…”

The mechanical property of age‐hardenable Al‐alloys is governed by the state of ageing, which determines the microstructure and consequently, their corrosion behavior which is a vital aspect for a number of applications. This article presents a comparative assessment of corrosion behavior of under‐, peak‐ and over‐aged Al‐Mg‐Si alloy. Corrosion characteristics have been determined via immersion tests in 0.1 M ortho‐phosphoric acid solution and intergranular corrosion (IGC) tests. Corroded surfaces are examined by field emission scanning electron micrographs‐energy dispersive spectroscopy and 3D optical profilometer. The obtained results reveal that the corrosion rate at a specific immersion time as well as the depth of IGC increases in the order for under‐, peak‐, and over‐aged states. Irrespective of the state of ageing, corrosion loss increases linearly but the rate of corrosion decreases rapidly with increasing immersion time. The dominant mode of corrosion in under‐aged alloy is identified as localized pitting, while peak‐aged is highly susceptible to IGC in contrast extensive pitting corrosion is observed for over‐aged alloy. The observed differences in corrosion behavior are explained considering characteristics of precipitates. Formation of β (Mg2Si) in case of over‐aged alloy and presence of inclusions like AlFeMnSi particles are found to accelerate pitting corrosion.

“…The wear resistance of special brasses was investigated by many researches and was found to be influenced by a few factors: relative proportions of α and β phases, solution hardening mainly affected by the presence of aluminum and overall hardness of the alloy [3,5,11]. Sun et al found that a great amount of nano-sized Mn 5 Si 3 precipitates dispersed in the microstructure of one type of brass containing Mn and Si after quenching at temperatures above 730 o C. It was widely believed that the dispersion of fine precipitates in the matrix could effectively increase hardness and wear resistance of the alloys [12][13][14][15]. However, the effect of nano-sized Mn 5 Si 3 precipitates on the wear behavior of special brasses has not been reported to date.…”

Special brasses containing Mn and Si possess high wear resistance due to the dispersion of hard Mn5Si3 particles. The effect of precipitation hardening on the wear resistance of a Cu–30Zn–3Al–3Mn–0.7Si based brass alloy was investigated. Dry sliding wear test was conducted using a block-on-ring configuration. The results indicated that finely, nanoscale Mn5Si3 particles precipitated from the matrix after annealing at 800 °C for 4 h, resulting in the increase of hardness from 240 to 278 HV. Both the wear loss and friction coefficient decreased, indicating the improvement of the wear resistance. From the examination of the worn surfaces, adhesive and abrasive wear were found to be the major wear forms. The adhesion and abrasion decreased after the precipitation-hardening treatment.
