Topics/Content:

  1. Definition and classification of steels,
  2. Fe-C phase diagram, phase properties
  3. Continuum concepts: relationship of strength, ductility, toughness
  4. Micromechanistics: strain hardening, Hall-Petch eq., hard vs. soft pins, solutes and interaction with dislocations, Peierl's stress
  5. Phase transformations in carbon steels, TTT diagrams, micrstructure v. mechanical properties. (w/ applied principles of nucleation and growth)
  6. Tempering reactions in plain carbon martensite, effect on properties, martempering, austempering, austenization, annealing, normalizing, and spheroidization.
  7. Hardenability - concepts, measures of, and test for. Classification and effects of alloying elements.
  8. Effect of alloying on tempering, secondary hardening, temper embrittlement.
  9. Common steel categories: HSLA, tool, and stainless steels.

Grading Plan:

15% Homework and Quizzes, 35% Midterm, 50% Final Exam

Professional Component Content:

Engineering Science: 50%, 1.5 credits

Engineering Design: 50%, 1.5 credits

Design Component Content:

Students learn how to design steel microstructures by thermomechancial treatment and alloying to balance performance objectives involving strength, ductility, toughness, and corrosion resistance.

Relation to Program Objectives:

1.This course brings together fundamental concepts taught throughout the curriculum with knowledge of how to apply those principles to arrive at desirable alloys and heat treatments for specialized application.

2.This course also directly teaches the relationship between microstructure and mechanical properties in ferrous systems.

Academic Integrity, Academic Misconduct

Academic misconduct may be found in any action that tends to distort the accurate assessment of any student’s individual accomplishments that are evaluated for the purpose of grading or conferring academic credit. Note that a student may be guilty of academic misconduct, for example, by cheating, collaborating, plagiarizing, or by allowing another student to cheat, collaborate, or plagiarize. Note also that the distortion applies, for example, to exams, homework assignments, and laboratory work. To the extent that any class activity (for example: attendance or participation) is used for evaluation for the purpose of grading or conferring academic credit, falsifying or distorting such activity, or permitting another student to falsify or distort such activity, represents academic misconduct.

Additional guidance about what represents academic integrity and misconduct, and related university-wide policies and procedures are available at the following locations:

Course-specific exceptions or amplifications to the departmental and university statements outlined above will be provided by the faculty instructor in writing, preferably as part of the course syllabus.

Note: Students should not request nor accept guidance on these matters from a teaching assistant, fellow student, or anyone other than the faculty instructor of record for this course.

Disabilities Statement

Any student who feels s/he may need an accommodation based on the impact of a disability should contact the Office for Disability Services at 614-292-3307 in room 150 Pomerene Hall to coordinate reasonable accommodations for students with documented disabilities. (URL: http://www.ods.ohio-state.edu/)

Advice on such matters is also available from the MSE department’s undergraduate adviser (1xx-6xx courses) and graduate coordinator (7xx-9xx courses) whose offices may be found in room 477 Watts Hall.
