“…Be segregation results in composition under-cooling and leads to grain refinement in the presence of suitable nuclei [15]. Azarbarmas et al [11] also reported that Be can enhance the nucleation in matrix alloy solidification process. The effect of a solute element on grain growth may be explained in terms of GRF (Eq.…”

“…Fine structures can be achieved by different means, such as fast cooling rate, heterogeneous nucleation, solute addition and melt agitation. Solute addition and heterogeneous nucleation, which are usually combined, have become common industrial practices for their simplicity and efficiency [11]. As major grain refinement mechanisms, solute and nucleation by adding alloying elements have been well studied in Mg and Al alloys systems [12,13].…”

“…Cao et al [18] reported that a trace of Be addition can cause a dramatic grain coarsening in Mg alloys at normal cooling rates. Nevertheless, Azarbarmas et al [11] certified that primary Mg 2 Si particles can be refined by Be. Bermingham et al [19] studied the grain refinement of Ti alloys with Be addition.…”

“…Furthermore, adding Be plays a very important role on improving many alloy systems' mechanical properties. For example, the ultimate tensile strength (UTS) of Al-15%Mg 2 Si composite has been enhanced by adding Be [11]. Considerable improvement in microhardness and tensile strength values with Be addition has also been observed [20].…”

Abstract:In this paper, the effect of different alloying elements on the ultimate tensile strength of Al-Mg2Si composites is theoretically studied. The feed forward back propagation neural network with sigmoid function is used. The extensive experimental results taken from literature are modeled and mathematical formula is presented in explicit form. In addition, it is observed that magnesium and copper have a stronger effect on the ultimate tensile strength of Al-Mg2Si composites comparison to other alloying elements. The proposed model shows good agreement with test results and can be used to find the ultimate tensile strength of Al-Mg2Si composites.

In this work, the effect of the addition of Bi combined with T6 treatment on microstructure and tensile properties of Sr-modified Al-15Mg 2 Si-3Cu composite is investigated. The results show that the refinement effect of Sr on primary Mg 2 Si is further enhanced via the combined addition of Bi. Interestingly, the truncated octahedral primary Mg 2 Si with the smallest size (11.5 μm) is obtained by adding 0.1% Sr and 1% Bi, which is distinctly different from the cubic shape modified by single 0.1% Sr. Consequently, as a precursor with strong diffusion of Mg and Si atoms during T6 treatment, the truncated octahedral primary Mg 2 Si is completely transformed into spherical morphology with the highest sphericity (0.92) solution treated at 500 C for 6 h. Additionally, further results reveal that the co-modification of Sr þ Bi is more efficient not only in promoting the spheroidization of primary Mg 2 Si, but also obtaining the fine dot-like eutectic Mg 2 Si than single modification of Sr or Bi. As a result, the tensile strength and elongation are significantly enhanced to 374 MPa and 4.75%, respectively. Thereby, this work offers an alternative co-modification system combined with T6 treatment to synthesize the spherical primary Mg 2 Si, which is helpful to prepare the high performance Al-Mg 2 Si composite.
