D...1 answer · 0 votes: 2a 600 3322 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. Answer the following questions by referring to the Cu-Al phase diagram shown below. (a) What is the lowest temperature at which a liquid can be found in a system of any composition of Cu-Al ? (b) A common alloy composition used in airplanes is 4 at. % Cu - 96 at. % Al. For this overall system composition, identify what phases are present at 500 degrees C. Select all phases present: Liquid ...

Al-Cu-Mg-Si system is the basis of a large number of wrought and casting aluminum alloys, e. g. 2XXX, ... experimental phase diagram and thermodynamic data for the Cu-Mg-Si system in 2006. According to Bochvar et al., most of the experiments available in The phase diagram of the Al-Cu binary system was reinvestigated 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, and in addition, to study the phase equilibria at 300 °C. The melting behavior of the θ-phase was confirmed to be peritectic. A metastable congruent ... phase being present between the c¢-phase and d-phase.

We will limit our discussion of phase diagrams of multi-component systems to binary alloys and will assume pressure to be constant at one atmosphere. Phase diagrams for materials with more than two components are complex and difficult to represent. An example of a phase diagram for a ternary alloy is shown for a fixed T and P below.

A first step is dissolving the solute in Al in the single-phase region. Figure 1 shows the Al-side of the Al-Cu phase diagram [8], which can represent the general precipitation-hardened alloy. The circle shows that for an Al-3.5Cu alloy, all Cu dissolves at 550ºC. Max solubility is 5.65%, while just 0.04% Cu dissolves in Al at room ...

Given the unexpected topology of the calculated phase diagram, a few remarks are in order. Although the presence of a Cu-rich bcc solid solution is surprising, given the assessments of Pelton [15] and of Saunders [16], this phase is consistent with the suggestion of Kraus et al. [19] and Old et al. [20] that a solid phase with about 20 at.

Phase Diagram of Copper-Aluminum. Here is the Aluminum - Copper phase diagram. Yes, it is quite complicated - but only if you alloy more then about 53 at% copper. The aluminum - Al2Cu phase diagram; i.e. the part left to the 53 at% Cu, is about as simple as you can have it for two atoms that cannot mix atomically at any large ratio.
