The Al-Si Phase Diagram 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.

forms with aluminum a series of nickel aluminides; one of them is Al 3 Ni ( in the diagram). Aluminum forms a eutectic with Al 3 Ni at 6.1 wt% nickel. The melting point of the Al-Al 3 Ni eutectic is 640 C and the volume of the Al 3 Ni phase in the eutectic is relatively large (about 9.7 wt%). Furthermore, the Al 3 Ni eutectic phase Aluminum-Copper Phase Diagram Another commonly used phase diagram is the aluminum-copper phase diagram, which is useful for understanding precipitation strengthening in Al-Cu alloys. The amount of copper present in an alloy is plotted on the x-axis. The phase fields of interest are the Al, θ, and Al+θ phase fields on the left hand side. Al – Zn (Aluminum – Zinc) Pierre Perrot and Jean-Claude Tedenac. Literature Data. The literature dealing with the Al-Zn phase diagram has been extensively reviewed by [] and updated by [1994Oka, 1995Oka].The phase diagram proposed and reproduced in [] is based on experimental phase boundaries reported in more than twenty papers and does not differ from previous evaluations []. However, due to problems in these alloys with microsegregation of the magnesium-zinc phase, they usually undergo rapid solidification.. Aluminum Cast Alloys Series 7xxx.x. According to the American classification, these alloys belong to the 7xx.x series. They have medium to high strength properties.. Annealing ensures good dimensional stability..
