Phase Diagrams

 

Catalog Data:

Phase diagrams of unary, binary, and ternary materials systems; thermodynamics and applications.Wi Qtr. Required.

Prerequisites:

4th year standing in engineering or permission of instructor. MSE 401 or equivalent. Not open to students with credit for MSE 521.01.

Time Distribution:

Three-48 minute lectures per week

Objectives:

Provide students with a working knowledge of how to read phase diagrams and use them to solve problems involving alloy and process design. Meet ABET Criteria 3 Outcomes a, e, i, j, and k.

Textbooks:

F. N. Rhines, Phase Diagrams in Metallurgy (McGraw-Hill, 1956, New York). Other supplemental reading will be provided.

Topics/Content:

See detailed list appended.

Grading Plan:

20% homework (8), 35% midterm (1), 45% final (1).

Professional Component Content:

Engineering Science: 2.5 credits or 83%.

Engineering Design: 0.5 credits or 17%.

Design Component Content:

Students learn to apply principles of phase diagrams to the design of alloys and material processes that involve multicomponent systems.

Relation to Program Objectives:

1. This course covers fundamentals of phase diagram topology and thermodynamics as it relates to metallic and ceramic systems (Objective 1).

2. Students are given homework assignments that require applying their fundamental knowledge to solving practical problems related to the design and heat treatment of ceramics and metal alloys (Objective 2).

3. This course prepares students for graduate research and employment in the areas of metal casting, welding, heat treatment, quality control and failure analysis as it relates to alloy phase stability (Objective 4).

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.
