Chapter 8 Phase Diagrams
phase diagrams is a type of graph used to show the equilibrium conditions between the thermodynamically-distinct phases; or to show what phases are present in the material system at various T p and compositions “equilibrium” is important: phase diagrams are determined by using slow cooling conditions ⇒ no information about kinetics |

Definitions and Basic Concepts
Binary – two components Equilibrium – stable over time Phase – a chemically and structurally homogeneous region Diagram – a map or drawing showing the general scheme of things • Phase diagrams are maps of the equilibrium phases associated with various combinations of composition temperature and pressure |

Binary Phase Diagrams
A phase diagram is a graphical representation of the equilibrium relations among phases typically as a function of one or more intensive variables such as chemical composition temperature pressure and the activity of a chemical component |
How many phases can a binary system have?
A binary system has two components; C equals 2, and the number of degrees of freedom is F = 4 − P. There must be at least one phase, so the maximum possible value of F is 3. Since F cannot be negative, the equilibrium system can have no more than four phases.
What is a Type 3 binary phase diagram?
This lecture begins with a quick review of Type 1 and Type 2 binary phase diagrams from the previous lecture. This class introduces Type 3 binary phase diagrams, characterized by partial solubility of components A and B, a change of state, and freezing point depression of both components.
How do you interpret a two-dimensional phase diagram?
The way in which we interpret a two-dimensional phase diagram to obtain the compositions of individual phases depends on the number of phases present in the system. If the system point falls within a one-phase area of the phase diagram, the composition variable is the composition of that single phase. There are three degrees of freedom.
What are the different types of phase diagrams?
35. Binary Phase Diagrams: Limited Solubility two-component phase diagrams: limited solid solubility (Type 3) binary phase diagram, liquidus, solidus, metallurgy, lenticular, syncline, eutectic, solvus, alpha and beta structures, lamellar structure
