Steel and Aluminum Alloys

Steel and aluminum processing will be studied to understand fundamentals such as the impact of impurities and phase transformations. The study of processing will provide an understanding of how the final properties are influenced by the sequence of processes from the extraction of metal from ore, through casting, hot deformation and heat treating. This understanding will enable the student to go beyond comparisons of standard handbook values and to recognize and understand how the fundamental metallurgical phenomena lead to different performance among the various steels and aluminum alloys. By examining the relationships among processes, microstructure, and properties, the course will provide the "know-how" for better design with steel, aluminum and competing materials.

Learning Objective:

  1. Describe current practice of steel and aluminum production in terms of the thermochemical unit processes
  2. Understand the differences between the main classes of commercial metal shaping processes and their intrinsic effects on microstructure
  3. Relate alloy microstructure to properties as measured in standard mechanical testing
  4. Interpret standards and specifications for processing and properties of different steel and aluminum alloy classifications
  5. Identify processing defects and predict their effect on material performance
  6. Specify alloy and processing route to achieve desired properties sets for particular applications
  7. Explain properties variability in terms commercial practice constraints
  8. Analyze critically the state of research on a particular current topic in steel or aluminum metallurgy

Description:

Steel and aluminum alloy processing will be studied to provide fundamental understanding of how the final properties are influenced by processing from the extraction of metal from ore, through shaping by casting, hot-working and cold-working, and heat treatment for control of microstructure. This understanding will enable the student to go beyond comparisons of standard handbook values and recognize the fundamental metallurgical phenomena leading to differences in performance among the main alloy classifications. By examining the relationships among processing, microstructure, and properties, the course will provide the "know-how" for specifying, designing, and manufacturing with steels and aluminum alloys. This approach will be broadly applicable to industrial metallurgical practice.
