MSE 8803L

Environmental Degradation of Materials

Instructor: Preet M. Singh

Room No. 246, IPST Building,

Tel: (404) 894 6641, preet.singh@mse.gatech.edu

Course Objectives: To introduce students to the basic principles of interaction between materials and environments and degradation in properties of engineering materials due to exposure to environment. To provide an understanding of fundamentals of corrosion processes so that students can recognize different corrosion mechanisms.

Textbook: D. A. Jones: Principles and Prevention of Corrosion , Macmillan Publ. Co., 1996.

Homework Assignments:

Only a portion of the homework assignments given will be graded. DO NOT underestimate the importance of completing ALL the homework assignments, since they will require understanding similar to that expected for exams and quizzes and will be representative of similar problems and questions given on exams and quizzes. Solutions of some of the homework will be posted on the course Web Site.

Research Topics and Presentations:

Graduate students are expected to show a greater depth of thought in their individual project and presentation. Additional class meetings will be held (dates to be determined later) and selected readings in more advanced texts will also be assigned. Students may do some experimental work, critically evaluate literature, and write a report on a given problem. The paper must have 1.5 line spacing and be 10 pages (max.) in length (not including references, figures and tables). It will start with an abstract and have introduction, body and summary. The paper will have at-least ten (10) references (maximum 20). The term paper must contain figures or data to support your conclusions or explanations. During the final weeks of class, each group will give a 15-minute presentation based on their research topic paper, and be prepared to answer questions from the class. Topics should be finalized by the end of January. Topics should be relevant to the corrosion issues in infrastructure or the chemical industry processes such as pulp and paper industry.

Class Schedule: Three hours per week (M, W, F) at 1:00 pm to 2:00 pm (183 Love Bldg.)

Office Hours : Wednesday and Friday (2:30 pm – 4:00 pm)
