“…Al-Mg-Si alloys are lightweight medium-strength heat-treatable Al alloys with an excellent combination of cost-effective engineering properties that makes them ideal for a wide range of applications, from the transportation [7,8] and building industries [9] to high-voltage power transmission [10]. Despite their outstanding advantages as structural materials, however, Al-Mg-Si alloys also have some disadvantages.…”

Al alloys offer excellent physical and mechanical properties, such as a low density, high specific strength, and good ductility. However, their low corrosion resistance has restricted their application in corrosive environments. There is a need, therefore, for a novel coating technology that is capable of improving the corrosion resistance of Al alloys. In the present study, we examined a steam-based method of forming a corrosion-resistant film on Al alloys. Al-Mg-Si alloy was used as the substrate. The cleaned substrates were set in an autoclave with ultrapure water as the steam source and processed using different temperatures and holding times, resulting in the formation of anticorrosive films on the alloy. FE-SEM images of the film surfaces showed that plate-like nanocrystals were densely formed over the entire surface. XRD patterns indicated that the film was composed mainly of AlOOH crystals. The potentiodynamic polarization curves revealed that the corrosion current density of the film-coated substrates significantly decreased, and that the pitting corrosion was completely suppressed, indicating that the corrosion resistance of the Al-Mg-Si alloy was improved by the film formed by means of steam coating.

“…Zastosowanie tego rodzaju, również niekonwencjonalnej, metody modyfikacji umożliwia dodatkowo wprowadzenie do ciekłego stopu pierwiastków i związków chemicznych powodujących poprawę jego właściwości użytkowych. Efekty modyfikacji siluminów eutektycznych i podeutektycznych z zastosowaniem sodu, strontu i antymonu oraz innych dodatków w procesie metalurgicznym są dobrze znane, czego dowodem są liczne publikacje [8,12].

“…melting, casting, homogenisation, extrusion and ageing. In every step of the manufacturing process, the chemical composition and the process parameters have a very complex influence on the final mechanical properties [3][4][5][6][7][8][9][10]. One of these steps is the homogenisation process, which is a crucial heat treatment before the extrusion process for AA production [11,12].…”

In this study, conditional average estimator neural networks (CAE NNs) were used for an analysis of the common influences of the cooling mode in relation to the ram speed, extrusion ratio, casting speed and casting temperature on the yield strength and the elongation of an extruded profile made from aluminium alloy (AA)6082. The obtained results from the analysis revealed very complex relationships between these parameters. In order to maximise the values for the yield strength and the elongation, the values for the ram speed, extrusion ratio, casting speed and casting temperature should be optimised in relation to the mode of cooling.Key words: AA6082, intermetallic phases, hot extrusion, mechanical properties, neural networks Izvleček V tem delu smo uporabili CAE (ang. conditional average estimator, slo. cenilka pogojnega povprečja) nevronske mreže za analizo skupnega vpliva načina ohlajanja v povezavi s hitrostjo bata, iztiskalnim razmerjem, hitrostjo ulivanja in temperaturo ulivanja na mejo tečenja in raztezek iztiskanega profila iz aluminijeve zlitine 6082. Dobljeni rezultati iz analize so pokazali kompleksen vpliv parametrov na mejo tečenja in raztezek. Da lahko izboljšamo vrednosti meje tečenja in raztezka, moramo vrednosti za hitrost bata, iztiskalnega razmerja, hitrosti ulivanja in temperature ulivanja optimizirati v povezavi z načinom ohlajanja.Ključne besede: AA6082, intermetalne faze, vroče izstiskavanje, mehanske lastnosti, nevronske mreže
