“…These large /?-phase AlsFeSi platelet sizes tend to prevent the flow of liquid metal during solidification, thereby reducing casting soundness. 26 ' 27 Tang et al} 1 illustrates that the dominant phase in all of the as-cast alloys studied is the 3r-phase. …”

“…It is accomplished by nucleation and growth process in the grains, while the size of the grains remains unchanged. 26 Since EDS measurements of the precipitates (Figure 4 and Table 2), with morphology not similar to Chinese script, we could conclude that most likely a-Al 8 Fe 2 Si phases are present in the precipitates. On the other hand, similarly as from LM images, with just observation, we cannot determine that the number of the inclusions increase with aging.…”

The influence of artificial ageing on the corrosion behaviour of the aluminium alloy AA 6063 in chloride-containing solutions was studied to determine the correlation between aging parameters and corrosion through the electrochemical parameters. The present study showed that LM and standard SEM imaging with EDS observation does not expose significant differences for the artificially aged aluminium. Nevertheless, a special statistical technique with observation of the larger area showed a significant increase of the smallest precipitates which are the initial sites for the corrosion. With electrochemical measurements, we corroborated that increase of corrosion rate is directly connected to the number of precipitates and not with the total area of exposed precipitates. Scanning electron microscopy observations combined with EDS measurements were used also to establish the type of precipitates in the studied alloy. Keywords: aluminium, artificial aging, SEM, electrochemical measurements Raziskovali smo vpliv umetnega staranja na korozijske lastnosti aluminijeve zlitine AA 6063 z namenom ugotoviti soodvisnost med staranjem in elektrokemijskimi parametri. V raziskavi smo dokazali, da zgolj standardni pregled s svetlobnim in vrsti~nim elektronskim mikroskopom v kombinaciji z EDS-analizo na prvi pogled ne poka`e bistvenih razlik med razli~no toplotno obdelanimi vzorci. Ugotovili smo, da s pomo~jo preiskave na ve~jem podro~ju in s statisti~no obdelavo lahko odkrijemo povezave predvsem med manj{imi izlo~ki in elektrokemijskimi parametri. S korozijskimi meritvami smo tudi potrdili, da je pove~anje korozijske hitrosti direktno povezano s {tevilom majhnih izlo~kov in ne s se{tevkom povr{ine vseh izlo~kov. S SEM-analizo v kombinaciji z EDS-analizo smo uporabili za dolo~itev vrst vklju~kov v preiskovani zlitini.

“…One of the requirements is always a reduced cost of manufacturing technology. Aluminum-silicon alloys are the cast alloys, which have production cost cheaper than the cost of pressure metal treatment technologies [3]. However, low cost of manufacturing technology faces with facts that alloying by different decreases the thermal conductivity [4].…”

“…[2]. Pure aluminum has one of the best thermal conductivity parameter compared to other metals, however, its plasticity does not allow using pure aluminum as constructive material, for example, for production of radiators and similar applications [3]. New electronic equipment in vehicles and aircrafts demands from industry new heat exchange solutions.…”

Temperature dependence analysis of thermal conductivity was carried out for series of aluminum alloys with 1% Fe (mass%) and different content of silicon starting from 0% to 6% (mass%). It is shown that the best alloy for heat exchange applications is alloy with 4% of silicon (mass%). Temperature dependence of thermal conductivity shows the strong decreasing character for silicon-alloyed samples in comparison to pure aluminum.
