The effect of alloying elements on thermal stability of five different near eutectic Al-Ce based alloys, i.e., Al-12Ce, Al-12Ce-4Si, Al-12Ce-0.4Mg, Al-12Ce-4Si-0.4Mg and Al-12Ce-4Si-0.4Mg-0.25Sr alloys were investigated. The alloys were heat treated at three different temperatures, i.e., 200 °C, 300 °C and 400 °C to establish the thermal stability. Binary Al-12Ce alloy consisting of α-Al and showed higher resistance to coarsening at all temperatures. Addition of Si decreases the thermal stability above 200 °C while combined addition of Si and Mg increases the thermal stability up to 300 °C. Addition of Sr to quaternary alloy was not beneficial to enhance the thermal stability.

“…The alloy system has been used for both the direct write and powder bed fusion. Manca [18] has reported high mechanical properties of Al-3Ce-7Cu in both hightemperature tension and compression testing via selective laser melting. Fine eutectic phases of Al 11 Ce 3 and Al 6.5 CeCu 6.5 were found in the microstructure.…”

Aluminum alloys containing small amounts of cerium have been investigated to improve the grain refining, casting characteristics, and mechanical properties of aluminum alloys. These additions were usually made at levels of 1% or less but did not produce appreciable improvements. Recent work has shown that additions between 4% and the approximate eutectic composition of 10% improve the high-temperature performance of aluminum alloys. Corrosion performance of aluminum alloys can also be improved through the addition of Ce. Traditional aluminum alloying elements such as magnesium and silicon can be used to control casting characteristics and thermal and physical properties. Cerium oxide is the predominate oxide in rare earth mining. Much of it is discarded after separation from the heavy rare earth oxides containing Nd and Dy. The beneficial use of Ce should reduce the cost of the more desirable rare earths. Results of using Ce as an addition to aluminum in multiple manufacturing methods such as additive manufacturing, extrusion, and casting are explored. The results show significant strengthening and improved mechanical property retention at higher temperatures than in other aluminum alloys and, in some compositions, show complete recovery of mechanical properties at room temperature when exposed to elevated temperatures as high as 500°C for 1000 hours.

“…Mehrpouya et al summarized in their review that 3D printing exhibits enormous market potential in industry 4.0 due to its significant advantages, such as time and materials saving and high design freedom [13]. Selective laser melting (SLM) is one of the most promising 3D printing methods mainly used to manufacture metal products by selectively melting the layers composed of metal powders [14][15][16]. SLM process is widely used to produce aluminum parts [4], titanium parts [5,6], biomedical parts [17], steels parts [7][8][9] and so on [18].…”

Selective laser melting (SLM) is an ideal method to directly fabricate products with high geometrical complexity. With low density and good corrosion resistance, aluminum alloys are widely used as important structural materials. Microstructures and mechanical properties of SLMed aluminum alloys have been recently widely studied. Corrosion behavior as a vital concern during the service of SLMed aluminum alloy parts has also drawn many attentions. Previous studies have found that SLM-processed aluminum alloys exhibit better corrosion resistance compared to the casted and wrought counterparts for both Al-Si alloys and high strength 2xxx Al alloys, which is mainly due to the unique microstructure features of SLMed Al alloys. For Al-Si alloys, with different shapes of Si networks, the different building planes show discrepant corrosion behaviors. Owing to the rougher surface with relatively larger numbers of defects, the as-printed surface is vulnerable to corrosion than the polished. Heat treatment has a negative effect on corrosion resistance due to the breakup of Si networks. The microstructure features correlated with the corrosion behaviors were also reviewed in this paper. Some suggestions on the future study of corrosion behaviors of SLMed Al alloys were put forward.
