Solubility Limitof a component in a phase is the maximum amount of the component that can be dissolved Phase Diagrams This common tangent construction can be extended to quite complicated situations, with several minima, which then give rise to quite complicated free energy curves and hence phase diagrams. For plotting a phase diagram we need to know how solubility limits (as determined by the common tangent construction) vary with temperature. + β) phase boundary at this temperature, or to about 2 wt% Cu. (b) From this same figure, the maximum solubility of Ag in Cu corresponds to the position of the α–(α + β) phase boundary at this temperature, or about 1.5 wt% Ag. 9.8 Cite the phases that are present and the phase compositions for the following alloys: Answer (1 of 4): Before it's answer you must know about that carbon present in Fe combine with it to form Fe3C. Means we can add carbon as much as possible until all Fe is converted into Fe3C. Thus weight %of C in Fe when all Fe converted into Fe3C will be max wt% of C in Fe. For this Let us as...

2.6 Structural analysis of Mg-RE alloys containing Gd. The maximum solid solubility of Gd in Mg is 23.5 wt.%. When added to Mg, Gd forms a Mg 5 Gd phase with a high melting point of 548 °C. Figure 2.1024 shows the as-cast microstructure (a) and the solution-treated micro-structure (b) of the Mg-14Gd binary alloy. This phase is a solid solution of carbon in FCC Fe with a maximum solubility of 2.14% C.

Definition of structures: Austenite is an interstitial solid solution of Carbon dissolved in (F.C.C.) iron. Maximum solubility is 2.0 % C at 1130°C. High formability, most of heat treatments begin with this single phase. It is normally not stable at room temperature. But, under certain conditions it is possible to obtain austenite at room temperature.

Hardness of pure material is very poor and maximum strength will be at the point of maximum solid solubility. Influence of Alloying Elements on Phase Diagram: Alloys elements addition always reduces eutectoid composition i.e.% of C while they may increase or decrease the eutectoid temperature.

The maximum temperature at which the two phase region exists is called the critical solution temperature. The critical solution temperature in this experiment is 70˚C. During this experiment, the temperature of the phenol-water system at miscible and temperature at which two phases separated is measured.

The maximum solubility of Cu in Al is equal to 2.5 at. pct at the eutectic temperature of 550 °C.[] The θ-phase (Al 2 Cu) was described for the first time by Owen and Preston[] and also by Friauf.[] The phase was characterized using XRD (single-crystal rotational method), and a tetragonal symmetry was found.

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.
