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. (1987). Al-Zn-Sn phase diagram - isothermal diffusion in ternary system. Materials Science and Technology: Vol. 3, No. 4, pp. 241-248. phase diagram in English was by Russian scientists at an international conference in the USA in 1964 (Fig. 2). 2 The same diagram appears in English translations of two Russian journals a year later, 3,4 and the phase diagram of these three publications is reproduced in various phase diagram handbooks. 5,6 With small excep- of PHAse Diagram (CALPHAD) approach. The thermodynamic descriptions of the binary Al-Sn, Al-Zn, and Sn-Zn systems from the literature were directly adopted, and the newly reported experimental phase equilibria, enthalpies of mixing, and activities of Al in the ternary liquid phase were taken into account.

Data Analysis Phase diagram and thermodynamic data for the Al-Zn system are used to optimize the parameter values of the thermodynamic models for the three phases. However, prior to carrying out the optimization, the available data are reviewed as given below. 3.1 Phase Diagram Data As mentioned earlier, there exist three phases in the Al-Zn ... 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 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 []. 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
