“…The acceptable plasticity could be observed after 2 h annealing. The tensile strength in the current paper was higher compared with the commercial Al-12Si alloys [ 22 ], and Al-12.5Si-0.6Mg-0.1Ti alloys (hot-rolling) [ 17 ]. However, the tensile strength was lower than that of the cryo-rolled A356 alloys [ 23 ] and warm-rolled Al-12Si-0.7Mg alloys [ 24 ].…”

In this paper, super-gravity solidification and cold-rolling were utilized to obtain Al-14.5Si alloys. The influence of annealing time on microstructure and mechanical properties of Al-14.5Si alloys was investigated. Our results indicated that high elongation was achieved by super-gravity solidification due to the submicron eutectic Si, making it possible to undertake the conventional cold-rolling. The yield strength (~214 ± 11 MPa) was significantly enhanced (~68.5%) after cold-rolling mainly due to high dislocation density. The coarsening of eutectic Si could be observed during annealing, which resulted in a decrease in yield strength. The elimination of internal stress and lattice distortion during annealing led to a decrease in micro-cracks/voids beneath the fracture surface during tensile testing, which in turn enhanced the elongation.

“…According to the wear test results, it was stated that the main wear mechanism is adhesion and delamination. In the study investigating the effect of Mg addition 0, 2, 3 and 4 Wt.% to Al-12Si eutectic alloy on casting quality and wear properties (Uludağ, 2020), the best wear properties (ball on-disc test) was obtained with the highest (4%) Mg addition. However, according to the lubricated (pin-on disc test) wear test result, it was reported that the addition of Mg had no effect on the wear properties.…”

Purpose Paper aims to an alloy development study was carried out to increase the mechanical properties of cylinder heads. Design/methodology/approach AlSi12 alloys are used to manufacture the compressor head cylinder by high-pressure casting for easy casting and superior properties. Therefore, 1.1%, 2.4% and 3.1% Mg were added to AlSi12. The microstructures of the produced samples were characterized by optical microscope, scanning electron microscopy, energy dispersive spectrometry and X-ray diffraction methods. Hardness and tensile tests as well as Charpy impact tests were performed. Wear tests were also carried out on the pin-on disc tester, and then the wear performance was examined on the tester, which simulates the actual operating condition. Findings AlSi12 has primary Si and eutectic Si in the Al matrix. However, alloys of Mg with AlSi12 have other intermetallics such as Mg2Si and ß-Fe, as well as primary Si and eutectic Si. Hardness and tensile strength as well as improved wear performance with increased Mg content. Originality/value In this study, wear performance test to simulate the operation of the cylinder head produced by high pressure casting from AlSi12 alloy moreover tensile test, hardness test and impact test were performed. Therefore, in this study, the wear performance of the compressor head produced by high-pressure casting method by adding three different amounts of Mg to AlSi12 alloy was investigated.
