Al-Mg-Si PHASE DIAGRAM The Al-Mg-Si phase diagram can be used for the analysis of many wrought alloys of 6XXX series and casting alloys of the 356.0 type, provided the concentration of iron impurity is low (Table 2.1). This diagram is also the basic diagram for casting alloys of the 512.0 type that are considered in Chapter 4.

Abstract The Al-Cu-Fe-Mg-Si phase diagram was assessed in the Al-Cu-rich region, including the solidification reactions and the phase distribution in the solid state.

Al-Si alloys differ from our "standard" phase diagram in that aluminium has zero solid solubilityin silicon at any temperature. This means that there is no beta phaseand so this phase is "replaced" by pure silicon (you can think of it as a beta phase which consists only of silicon).

The phase diagram contains two solid solution phases (α-Al) (FCC_Al) and diamond cubic Si (Diamond-A4), a liquid phase, and three mixed phases; FCC_Al + Diamond-A4, liquid + FCC_Al, and liquid + Diamond A4. The melting points of Al and Si are 932.77 and 1687.73 K (659.62 and 1414.58 °C), respectively.

The Al-Si phase diagram, a diagram of considerable commercial significance, is the starting point for developing more complex alloys and for understanding their behavior. Si is a common impurity in aluminum alloys, but it is also a deliberate alloying addition in both cast and wrought Al alloys.

To apply the basic concepts of phase diagrams to binary aluminium alloys. To extend the discussion to an outline of ternary phase diagrams, and to show how a so-called pseudo-binary section can be applied with benefit to the Al-Mg-Si system for alloys balanced in Mg2Si.

Aluminium-silicon casting alloys

The binary Al-Si phase diagram was initially studied by Fraenkel of Germany in 1908. It is a relatively simple binary diagram where there is very little solubility at room temperature for Si in Al and for Al in Si. Thus, the terminal solid solutions are nearly pure Al and Si under equilibrium conditions.

It was found that there is a narrow ternary phase field of Al+Mg 2 Si+liquid in the diagram. At the pseudoeutectic composition of Al-13.9 wt-%Mg 2 Si, a pseudoeutectic reaction takes place between the temperatures of 583.5 and 594°C. The solubility of Mg 2 Si in Al at 583.5°C is calculated as 1.91 wt-%.

The copper is used for precipitation hardening (Al 2 Cu, Al 5 Mg 8 Cu 2 6), should that be necessary.Iron is to be avoided if possible, since it can form plate-like precipitates (Al 5 FeSi) which embrittle the casting and can block the flow of liquid metal in the mould. The strontium, when added delibrately, helps to modify the shape of the silicon, rather as does sodium.

Al-Si diagram is a eutectic diagram where solid solubility at least of aluminium in silicon is negligible, and maximum solubility of silicon in aluminium (at eutectic temperature) is 1.65%. The eutectic composition is 12.7% silicon. Fig. 3.18 illustrates this diagram and photomicrographs of alloys at room temperature.

A general view of the Al-Fe-Si phase diagram, the projections of the liquidus and solidus surfaces in the aluminum corner in the diagram are given in Figure 1.1. These data suggest that a decrease in the Hquidus and solidus temperatures (in Al-rich alloys) is primarily due to the concentration of sihcon, the effect of iron being much smaller.

Si/Al Phase Diagram Most Si/Al alloys are cast near this eutectic point, they are cheap to manufacture; but cuboid Si flakes cause brittleness. Doping with 0.01% Na alters the compositional and temperature of the eutectic point (red lines): Alloy 2, which has the same relative amounts of Si and Al, now preciptates in a hypoeutectic fashion.
