Unformatted text preview: Professor Mohamad Al-Sheikhly Department of Materials Science and Engineering and University of Maryland College Park, MD Introduction to Materials Engineering ENMA 300 and ENME382 Description: Structure of materials, chemical composition, phase transformations, corrosion and mechanical properties of metals, ceramics, polymers and related materials. Material selection in engineering applications. Prerequisites: ENES 220 or permission of the department. Class Schedule: MWF....... 9:00 am- 9:50am (CSI 3117) Laboratory: M......... 2:00pm- 2:50pm (KEB 1135) Textbook: Callister, William D. Jr., Fundamentals of Materials Science and Engineering: An Integrated Approach 3rd Ed., John Wiley and Sons, 2008 ISBN 9780470125373 (Hardcopy and electronic versions are both acceptable.) Course Objectives: The main objective of this course is to understand the structure-property relationships in materials science and engineering. A student completing this course satisfactorily should be able to: 1. Identify features of crystal structures and their relationship to strengthening and failure mechanisms of materials. 2. Understand the similarities and differences in the microstructure of metals, ceramics, polymers, biomaterials and nanomaterials and how these relate to their mechanical, thermal, electrical, magnetic and optical properties. 3. Interpret features of binary phase diagrams and identify phase transformations. 4. Identify structure-property relationships in engineering materials and how these apply to materials selection in specific engineering problems. 5. Address basic concepts of engineering ethics. Topics Covered: 0. Engineering ethics: will be covered on an exam. I. Introduction - Chapter 1 II. Atomic Structure and Interatomic Bonding - Chapter 2 1. Atomic Structure and the Periodic Table 2.

Phase transformations- basic concepts, kinetics (including TTT and CCT curves), metastable vs. stable transformations including displacive (martensitic) transformations, microstructure development 5. Precipitation and dispersion hardening 6. Glass transition curves and crystallization of polymer and ceramic glasses XI. Corrosion and Degradation of Materials - Chapt. 16 1. Degradation of Metals (Electrochemical and chemical corrosion, Oxidation and Hydrogen Embrittlement) 2. Degradation of Polymers (Swelling and dissolution, bond rupture, weathering) 3. Ceramics and semiconductors Grading: Midterm I Midterm II Final Exam Homework Pop Quizzes 22% 22% 36% 15% 5% Fri., March 7, 2011 Fri., April 8, 2011 Mon. May 17, 2010 8:00 am – 10:00 am (Sched. Classes) (Expect 10 or 11 assignments) (Intended to evaluate understanding and reinforce important concept & attendance) Homework is intended to give students a chance to practice with concepts and critical thinking skills. Students who complete the homework tend to do better on exams and in the course. Not all assigned problems will be graded but detailed solutions will be available. While general concepts may and should be discussed with classmates, students should regard homework as an individual assignment except when team exercises are assigned. 2 Professor Mohamad Al-Sheikhly Class attendance is strongly encouraged. Material not in the textbook will be covered and there will be several unannounced quizzes. A lack of attendance and/or class participation will affect grades. Course Website: https://bb.eng.umd.edu (ENMA 300) CourseEvalUM Spring 2010: Your participation in the evaluation of courses through CourseEvalUM is a responsibility you hold as a student member of our academic community. Your feedback is confidential and important to the improvement of teaching and learning at the University as well as to the tenure and promotion process. CourseEvalUM will be open for you to complete your evaluations for semester courses sometime in May 2010. Please go directly to the website (www.courseevalum.umd.edu) to complete your evaluations . By completing all of your evaluations each semester, you will have the privilege of accessing online, at Testudo, the evaluation reports for the thousands of courses for which 70% or more students submitted their evaluations. • Academic Accommodations: If you have a documented disability, you should contact Disability Support Services 0126 Shoemaker Hall. Each semester students with documented disabilities should apply to DSS for accommodation request forms which you can provide to your professors as proof of your eligibility for accommodations. The rules for eligibility and the types of accommodations a student may request can be reviewed on the DSS web site at http://www.counseling.umd.edu/DSS/receiving_serv.html. • Religious Observances: The University System of Maryland policy provides that students should not be penalized because of observances of their religious beliefs, students shall be given an opportunity, whenever feasible, to make up within a reasonable time any academic assignment that is missed due to individual participation in religious observances. It is the responsibility of the student to inform the instructor of any intended absences for religious observances in advance. Notice should be provided as soon as possible but no later than the end of the schedule adjustment period. Faculty should further remind students that prior notification is especially important in connection with final exams, since failure to reschedule a final exam before the conclusion of the final examination period may result in loss of credits during the semester. The problem is especially likely to arise when final exams are scheduled on Saturdays. • Academic integrity: The University of Maryland has a nationally recognized Code of Academic Integrity, administered by the Student Honor Council. This Code sets standards for academic integrity at Maryland for all undergraduate and graduate students. As a student you are responsible for upholding these standards for this course. It is very important for you to be aware of the consequences of cheating, fabrication, facilitation, and plagiarism. For more information on the Code of Academic Integrity or the Student Honor Council, please visit http://www.studenthonorcouncil.umd.edu/whatis.html The University of Maryland is one of a small number of universities with a student-administered Honors Code and an Honors Pledge, available on the web at http://www.jpo.umd.edu/aca/honorpledge.html. The code prohibits students from cheating on exams, plagiarizing papers, submitting the same paper for credit in two courses without authorization, buying papers, submitting fraudulent documents, and forging signatures. The University Senate encourages instructors to ask students to write the following signed statement on each examination or assignment: "I pledge on my honor that I have not given or received any unauthorized assistance on this examination (or assignment).” Contribution of the course to the professional component: This course is an introductory course in Materials Science and Engineering. It teaches the fundamentals of structure – property relationships in materials, which are essential in the selection of materials for specific applications, which is important in the development of all engineers. Relationship of course to program objectives: This course serves as the foundation for the Undergraduate Program in Materials. All other courses build up on the basic concepts introduced in this course. 3 Professor Mohamad Al-Sheikhly Instructor: Professor Mohamad Al-Sheikhly Room number : 2309 D Building 090, Chemical and Nuclear Engineering Building Tel: (301) 405-5214 Email: mohamad@umd.edu Office Hours (tentative): Mon. 10-11:30 am, Wed. 10-11:30 pm AND by appointment Prepared: January 13, 2011 4 ...
