“…To further improve their performance, large amounts of refractory and noble elements such as Ni, Mo, Ta, V and Sc were added [4][5][6]. Alternatively, new manufacturing techniques, including spray forming and thixoforming, have been developed [7][8][9][10][11].…”

“…To improve the mechanical properties of cast aluminium alloys, various casting technologies have been proposed, such as squeezed casting [1], melt drag twin-roll casting [2], semisolid rheo-casting [3], and heated mould continuous casting (HMC) [4]. Commercial cast aluminium alloys (ADC12) synthetised via the HMC process exhibit good tensile strength properties; specifically, which is more than 1.5 times higher than that of ADC12 alloys obtained via the conventional die casting process [5]. Furthermore, artificial aging has been carried out to obtain high-strength HMC-ADC12 alloys (382 MPa [6]); during this process, severe CuAl 2 precipitation occurs.…”

To enhance the mechanical properties of cast Al–Si–Cu alloys (ADC12), 0.3% of carbon nanotubes (CNTs) was added. The cast ADC12–0.3%CNT samples were synthesised via heated mould continuous casting for the creation of fine grains, and the artificial aging process was conducted at 173°C for 13 h to obtain precipitation hardening. The reinforcement and refinement of eutectic Si and precipitates (Al2Cu and Mg2Si) were achieved by adding CNTs, which leads to a high tensile strength of about 450 MPa and a relatively high ductility of about 10%. The obtained tensile strength and 0.2% proof stress are more than twice as high as those of the conventional cast ADC12 alloy. The refinement of the microstructures could be due to the interruption of their growth caused by the CNTs.

“…Some researchers have investigated the mechanical properties of OCC-Al alloys, showing excellent tensile and fatigue properties. This can be explained by that their unidirectional microstructures, low defect density, and uniformly oriented lattice structure [6][7][8]. Therefore, it is believed that the OCC process is useful in the automotive industry.…”

To improve the mechanical properties of the casting alloys, various attempts have been made to use alternative casting technologies. The Ohno continuous casting (OCC) process is a unidirectional solidification method, which leads to high-quality cast samples. In this study, the Al-Si-Cu-Mg alloy was cast at casting speeds of 1 mm/s, 2 mm/s, and 3 mm/s, by the OCC process. The aim of this study is to investigate the effects of the casting process parameters, such as casting speeds and cooling conditions, on the crystallization characteristics and mechanical properties of OCC-Al-Si-Cu-Mg alloy. Particularly, secondary dendrite arms spacing of α-Al dendrites in OCC samples significantly decreases with increasing casting speed. Moreover, the mean tensile strength of the samples, produced at the highest casting speed of 4.0 mm/s, is significantly higher than that for the samples produced at a casting speed of 1.0 mm/s.
