PPT-Ternary Phase Diagrams Single Eutectic

Two Eutectic Points Peritectic and Eutectic Points Solid solution More accurately represent real igneous rocks Phase Rule df C P 1 T can be plotted as contours A B C Cotectic Ternary. Phase diagram: plot of pressure vs. Temperature summarizing all equilibria between phases.. Given a temperature and pressure, phase diagrams tell us which phase will exist.. Features of a phase diagram:. DEVELOPMENT OF MICROSTRUCTURE IN. EUTECTIC ALLOYS. Depending on composition, several different types of microstructures are possible for the slow cooling of alloys belonging to binary eutectic systems.. The Structure and Dynamics of Solids. Phase . Diagrams. Equilibrium cooling. Multiple freezing sites. Polycrystalline materials. Not the same as a single crystal. The compositions that freeze are a function of the temperature. . EQUILIBRIA. Ternary Systems. Types:. (Liquid –Vapor) ternary systems. (Liquid – Solid ) ternary systems. Section 12. Today’s Topic :. The Three component system , L-V type. Degree of freedom analysis. Michael S.

Abstract: There is base 10 and base 2 and base 16 (hexadecimal) notation but why not base 3 (ternary) and in particular . GLY 4200 . Fall, 2016. 2. Binary Diagrams. Binary diagrams have two components. We therefore usually choose to plot both T (temperature) and X (composition) with pressure held constant. P-X (T fixed) or P-T (X fixed) are also possible.

We therefore usually choose to plot both P (pressure) and T (temperature) since composition is not a variable. Examples. Given a temperature and pressure, phase diagrams tell us which phase will exist.. Features of a phase diagram:. Triple point: temperature and pressure at which all three phases are in equilibrium. . Vapor-pressure curve: generally as pressure increases, temperature increases.. E. nergy vs. Composition . C. urves.

We therefore usually choose to plot both T (temperature) and X (composition) with pressure held constant. P-X (T fixed) or P-T (X fixed) are also possible. Metamorphic Rock Associations.
