Learning Outcomes of the course unit	By the end of the course, the students should be able to: Explain and comprehend the Binary Alloy Phase Diagrams of Completely Miscible Systems (Equilibrium and Non-Equilibrium Cooling Curves, Liquidus, Solidus, Phase Fields, Type of Phases, Lever Rule), calculate the %Phase Composition, %Chemical Composition of Each Phase and draw the corresponding microstructures. Know very well the Cu-Ni Alloy System, Binary Alloy Phase Diagrams of Immiscible Systems Containing Three-Phase Reactions (eutectic, eutectoid, peritectic, peritectoid, monotectic), calculate the %Phase Composition, %Chemical Composition of Each Phase and draw the corresponding microstructures. Describe the Fe-C Phases and their Mechanical Properties (Ferrite, Austenite, Cementite, Martensite), comprehend the Time-Temperature-Transformation for Eutectoid Steel (TTT Diagrams) and use it in different applications. Design a particular Steel or a Stainless Steel, describe how to heat-treat it, what kind of microstructure will develop and what will be its final mechanical properties. Explain the different Processing Methods of Advanced Ceramics (Powder metallurgy, milling, die-pressing, Sintering) and the different Classification of Polymers (Thermoplastic, Thermosetting, Elastomers) and their engineering applications. Describe the different types of Composite Materials (Particulate, Fiber and Laminar Composites), their processing and suggest different composites for different engineering applications. Explain the fundamentals of Corrosion (Chemical Corrosion, Electrochemical Corrosion, Oxidation) and use the existing methods to prevent it. Use non-destructive Testing Methods, identify proper instrumentation and apply them to different engineering materials. Use thermocouples to measure temperature profiles and optical microscopy to observe microstructures.
