Chapter 4 Summary Concepts: Alloys, Solid solutions, Intermediate phases, phase, Substitutional solid solution, Interstitial solid solution, Metallic compounds, Intermetallic compounds Equilibrium Phase Diagrams, Solubility, Intermetallic Compounds stoichiometric intermetallic compound, non- stoichiometric intermetallic compound Steels, hypoeutectoid steels, hypereutectoid steels, Phase Diagrams: A graphical means of representing the phases of a metal alloy system as a function of composition and temperature (Cu-Ni) Alloy System: Characteristics: Solid solution alloy throughout entire range of compositions below the solidus No intermediate solid phases in this alloy system A mixture of phases (solid + liquid) in the region bounded by the solidus and liquidus Application: Determining Chemical Compositions of Phases The overall composition of the alloy is given by its position along the horizontal axis The compositions of liquid and solid phases are not the same Inverse Lever Rule
