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 ...

The thermodynamics of precipitation in 7075 Al-alloy can best be understood by referring to the binary phase diagram of Aluminum-Zinc in the aluminum-rich region in Figure 8-1. Figure 8-1: Schematic phase diagram for an age hardenable alloy. When the aluminum-zinc alloy of less than 5-6 wt% zinc is heated to temperature just above the solvus

The phase diagram of the Al-Cu-Zn ternary system was re-investigated experimentally. The current study was designed to contribute to a better description of those parts of the phase diagram, which are disputed in the current scientific literature. Mutual relations in the family of ternary intermetallic phases τ with cubic, rhombohedral and modulated structure at temperatures 400 °C and ...

According to the EDS point analyses and the Al-Zn phase diagram shown in Figure 4, the white phase is confirmed to be the ?- Zn, showing a continuous reticular shape in the middle zone of the...

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 system, i.e., the liquid, fcc (Al) and hcp (Zn) phases [58Han, 83Mur].

-Al-Zn alloys have also been investigated [22-25]. The phase diagram of Cu-Al-Zn system, due to technical importance, had been investigated in a number of studies and many reviews of experimental data have been conducted. A detailed review of this data was pre-sented by Liang and Chang [26]. However, a serious

The Al-Zn binary system was first assessed by Murray [ 31 ]. However, the calculated phase diagram was not in good agreement with the experimental data available in the literature. Later, Mey and Effenberg [32 ] re-assessed this system, but the calculated phase boundaries of the (Al)fccin the two-phase region ((Al) fcc +(Zn) hcp

Al Sc phase diagram Apparently, the rst publication of the complete Al Sc 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

pected.2,5,6 The phase diagram of the system Al-Zn has been defined on the basis of a number of papers and accepted in the literature.2,4 The ageing time necessary to approach the equilibrium state, in which the α(M/β)-phase, depleted in Zn, is in equilibrium with β precipi-tates, decreases with the increase of x(Zn) and the age-ing temperature.

Based on the assessed thermodynamic parameters by Ghosh et al. , the phase diagram and thermodynamic properties of the Mg-Zn system are calculated as shown in Figures 3, 4, and 5. They [ 22 ] considered all the available experimental data including the recent measurements of enthalpy and entropy of formation and heat capacity (cp) of the ...

Ternary phase diagram of Al-Cu-Zn alloy. The line crosses the zone composed by the α, η and τ phases [8]. Figure 6 shows a ternary phase diagram of Al-Cu-Zn alloy to 200°C, at atmospheric pressure. A diagram of this kind does not exist in the literature at room temperature and all that's left is to think that keep the phases present of ...

The phase diagram of Zn-Sn binary system is a simple one of eutectic type [14]. The temperature of the eutectic reaction is 198.5°C. Al-Sn system [14] is also simple eutectic type with the eutectic reaction at 228.5°C. Equilibrium Al-Zn phase diagram [14] comprises of the eutectic reaction at 381°C and eutectoid reaction at 277°C.

We decided to make five different samples. The two original samples, 100% Al and 100% Zn, one 80% Al and 20% Zn, one 50/50 Al-Zn and one 80% Zn 20% Al. • Once all of the samples were weighed, we began melting the samples, followed by pouring the melted samples sandcast mold to let them cool. •
