  5. What is Ferrous Metallurgy? Historically, ferrous metallurgy is the foundation for virtually everything we know about the structure and properties of metals. • Process Metallurgy • Extraction and Refinement • Physical Metallurgy • Thermodynamics and kinetics of microstructural transformations • Mechanical Metallurgy • Deformation behavior and failure mechanisms

  6. Ferrous Metallurgy – Course Outline The Manufacture of Iron and Steel Physical Metallurgy of Ferrous Alloys The Heat Treatment of Steels and Cast Irons Properties of Steels and Cast Irons

  7. I. The Manufacture of Iron and Steel • Iron Ores • Recovery of Iron • Thermomechanical Processing • Standard Product Forms • Classification of Steels & Irons • Steelmaking Processes • Control of Ingot/CC Structure • Melt Chemistry & Alloying

  11. What should I already be familiar with? • Thermodynamics of Materials • Phase diagrams • Gibbs free energy • Physical chemistry MatE 212 D.R.Gaskell, Introduction to Metallurgical Thermodynamics, Chapters 10, 11, and 12. • Kinetics of Phase Transformations • Thermal activation • Diffusive processes • Nucleation and growth MatE 315 D.A. Porter and K.E. Easterling, Phase Transformations in Metals and Alloys, Chapters 2.1-2.3, 3.4, 5.1-5.4. • Mechanical Metallurgy • Plastic deformation • Elementary dislocation theory • Strengthening mechanisms MatE 318 and 342 G.E. Dieter, Mechanical Metallurgy, Chapters 5 and 6. • Characterization Methods • Optical Microscopy • Scanning electron microscopy • X-ray diffraction MatE 214 Richardson, Optical Microscopy for the Materials Sciences; Goldstein et al., SEM and X-Ray Microanalysis; Cullity, Elements of X-ray Diffraction.

  12. What should I gain from this course? A general knowledge of the various methods available for the production of ferrous materials and their associated characteristics with respect to engineering properties. Practical capabilities with respect to the identification and control of microstructures in steels and cast irons. An understanding of the relationships between microstructure, chemistry, processing, and properties in ferrous alloys. A general appreciation for the wide variety of microstructures and properties available in ferrous alloys. The ability to assess, select, and specify ferrous alloys and processing routes for particular design applications. The ability to apply basic metallurgical principles to engineering problems related to the design, production, and application of ferrous alloys.
