1
Thermodynamics and Phase Diagrams
Alexandra Navrotsky
2
Phase Separation
3
Other exsolution topologies
4
Complete solubility in both high T and low T phases: vapor-liquid or liquid-solid equilibrium
5
Complete solubility in liquid, none in solids: eutectic
6
Eutectic, Solid Solution, Free Energies
7
Development of limited solid solubility acd a eutectic from a solid solution
8
Development of compound formation from a eutectic
9
Au-Cu: ordered compounds at low T, complete solid solution at highT
10
Au-Cd: stable compounds to the liquidus
11
Au-Na: stable stoichiometric compounds
12
Au-Ni: miscibility gap almost to the solidus
13
Au-Co: different structures, no compounds, eutectic, positive deviations from ideality in melt also
14
Ternary system: triangle representation
15
Ternary exsolution topologies
16
Ternary eutectic
17
Ternary Eutectic
