“…Besides, it has a homogeneous equiaxed dendritic structure and more uniform distribution of the second phases in the interdendritic regions. This is in agreement with some of the literature concluding that even minor Zr addition has considerable effect on the microstructure refinement of aluminium alloys due to presence of Zr-bearing precipitates [2][3][4][5][6][7][8][9][10]. Microstructures of the alloys after homogenization are shown in Figure 1 c and d. After the homogenization of the alloys at 580 °C, interconnected plate-like β-AlFeSi intermetallics may transform to more spheroidal discrete α-AlFeMnSi phase.…”

“…Their pinning effect can have a huge impact of improving the microstructural properties of aluminium alloys. These precipitates can transform to the equilibrium D0 23 -Al 3 Zr structure during prolonged heat treatment. In 6xxx aluminium alloys with high content of Si, the (Al,Si) 3 Zr precipitate which has D0 22 structure is formed in place of the equilibrium D0 23 structure through substitution of Al by Si [7].…”

“…Alloying elements affect not only the microstructural features but also physical and mechanical properties. Among these alloying elements, Mn is used to control the grain structure resulting in the enhancement of strength [1][2][3][4][5][6]. The wear performance of these alloys can be improved by adding of Si and Cu also has positive effect on the corrosion resistance.…”

“…The wear performance of these alloys can be improved by adding of Si and Cu also has positive effect on the corrosion resistance. New trends on the enhancement of mechanical properties rely on the addition of Zr, Hf, Sc and V. Several reports revealed that these elements provided a combination of grain refinement and precipitation hardening effects to improve the properties [2][3][4][5]. The addition of Zr leads to form Al 3 Zr precipitates during solidification [7][8].…”

In this study, Al-0.80Mg-0.85Si alloy was modified with the addition of 0.3 wt.-% zirconium and the variation of microstructural features and mechanical properties were investigated. In order to produce the billets, vertical direct chill casting method was used and billets were homogenized at 580 °C for 6 h. Homogenized billets were subjected to aging practice following three stages: (i) solution annealing at 550 °C for 3 h, (ii) quenching in water, (iii) aging at 180 °C between 0 and 20 h. The hardness measurements were performed for the alloys following the aging process. It was observed that peak hardness value of Al-0.80Mg-0.85Si alloy increased with the addition of zirconium. This finding was very useful to obtain aging parameters for the extruded hollow profiles which are commonly used in automotive industry. Standard tensile tests were applied to aged profiles at room temperature and the results showed that modified alloy had higher mechanical properties compared to the non-modified alloy.

Abstract:The effect of the vanadium addition on the microstructure, the precipitation behavior, and the mechanical properties of the Al-5.0Cu-0.4Mn alloy has been studied. The as-cast Al-5.0Cu-0.4Mn alloy was produced by squeeze casting and the heat treatment was carried out following the standard T6 treatment. It is shown that, with the addition of V, grain refinement of aluminum occurred. During heat treatment, the addition of V accelerates the precipitation kinetics of θ (Al 2 Cu) phase along the grain boundaries, and promotes the growth rate of the θ in the α(Al) matrix. Meanwhile, the addition of V retards the precipitation of T (Al 20 Cu 2 Mn 3 ) phase. The tensile strength of the Al-5.0Cu-0.4Mn alloy increases with the increase of V content, which can be explained by combined effects of the solid solution strengthening and precipitate strengthening. However, excessively high V addition deteriorates the mechanical properties by forming brittle coarse intermetallic phases.
