The Al-Mg phase diagram has the following intermediate phases: Mg 2 Al 3 (denoted β; cubic, space group \(Fd\bar{3}m\)), R or ɛ (rhombohedral) and Mg 17 Al 12 (denoted γ; α-Mn type cubic). The Al-Zn phase diagram [Massalski2] contains no intermediate phases. A miscibility gap occurs in the Al-based face centered cubic (fcc) solid solution below 351 °C, where the fcc phase splits into (Al ...

Aluminum alloys are economical in many applications. Ref. 1, the phase diagram of the Al-Zn system has been established and ac-cepted in the literature.1,2 Keeping in mind the mentioned experimental and theoretical evidence, the Al-Zn alloys are very suitable for studying the mechanism and kinetics of phase transitions in supersaturated solid solutions. This Al-Cu phase diagram shown only goes up to ca 60%, by weight, of Copper. and is "split" at around 54wt%Cu by a particular phase. This "split" means that the two parts of the diagram must be considered separately. The diagram up to the 54% point is very similar to the "standard" phase diagram. Intermetallic phases are not named " or ... The Al-Mg-Zn phase diagram is the basic diagram for such alloys as 7104, 7005, 7008, etc. (Table 6.1), and can be also, albeit with some restrictions, applied to high- strength Al-Zn-Mg-Cu alloys containing less than ^1% Cu, e.g. 7076 and 7016

Effect of silicon content on the solidification range in Al-Zn alloys. Detailed examination of the solidification microstructure under the SEM confirmed that, apart from its apparent effect on the cooling rate dependence of SDAS, the most significant ... The appearance of the ε phase during the welding process can severely weaken the welding strength of dissimilar metals of Mg-Zn-Al alloy systems. An understanding of the accurate phase diagram, especially the equilibrium phase relation around the ε phase, is thus of particular importance. However, the phase interrelation near the ε-Mg23(Al, Zn)30 phase has not yet been fully studied. Abstract. This article is a compilation of binary alloy phase diagrams for which zinc (Zn) is the first named element in the binary pair. The diagrams are presented with element compositions in weight percent. The atomic percent compositions are given in a secondary scale. For each binary system, a table of crystallographic data is provided ...

2. Mg-Al (Magnesium-Aluminium) This is the most important Mg binary phase diagram because Al is added to mg in most of the commercial types of Mg alloys. Several researchers [ 81 - 95] studied the liquidus, solidus, and solvus lines of the Mg-Al system.

A phase diagram (or equilibrium diagram) is a diagram with T and composition as axes, showing the equilibrium constitution. The phase diagram of an alloy made of components A and B, for all combinations of T and X B, defines the A-B system. Binary systems have two components, ternary systems three, and so on. Commercial alloys may
