Course Objective: Every discipline of engineering is concerned with utilizing materials to design and manufacture products, from microelectronics to bridges to the space shuttle. The faculty of the College of Engineering at Wayne State University agree that every graduate from the College should have some background in materials. The objective of this course is to give each of you some exposure to materials science, including the atomic and microscopic structure (microstructure) of materials, how the microstructure affects the macroscopic properties of a material, and how the microstructure can be tailored through processing to achieve the material properties of interest. This course will cover metals, polymers, ceramics, composites and electronic materials, in addition to some fundamental concepts in materials which are applicable to most or all of the material groups listed.

Text: William D. Callister, Materials Science and Engineering: An Introduction, 4rd Edition, John Wiley & Sons, New York, 1997.

Class Meetings: Class will meet from 8:30 a.m. to 9:25 a.m. on Mondays, Wednesdays and Fridays in Room 1500 Engineering. No attendance will be taken, but material not in the text will be presented and will be subject to testing. Each student is responsible for all material in the lectures and in the relevant portions of the text unless directed otherwise.

Quiz: Each quiz section will meet every week. Scheduled quizzes will be given at the beginning of most of these sessions and will collectively contribute 5% to your final grade. Therefore, you must attend quiz sessions on a regular basis. No makeup quizzes will be given, but the two quizzes with the lowest grades will be dropped. You should attend the quiz session assigned by the Registrar. Attendance at other times for additional help is allowed, however you will only be allowed to take a quiz at your assigned time.

Laboratory: You should have registered for one laboratory section. The laboratory portion of the course will meet in 2348 Engineering for two hours every other week, as arranged in lecture. The laboratory will begin the week of September 8th. A total of six experiments must be performed and a report for each must be written and submitted. Lab. reports must be typed!! Lab reports will be written as a group (2-3 students) project. Lab reports will be due one week after the experiment is performed, except for the Tensile Test experiment. This experiment/lab report will be completed as a group effort, the report will be counted double for grading and it will not be due until your next lab meeting, two weeks later. Additional detail is provided in the lab manual. Laboratory work (including reports!!!) will constitute 7% of your course grade. Penalties will be applied for late reports at a rate of two points per week or fraction thereof (Max. score for a lab report is 10 points). Failure to complete the laboratory work will result in failure in the course, no matter how good your exam performance. The $20 material fee must be paid at your first scheduled laboratory session. No one will be allowed in the laboratory without a material fee card. Safety glasses must be worn in the laboratory at all times.

Homework: Homework sets will be assigned regularly during the semester. Two homework grades will be dropped with the remainder used to make up 5% of your final grade. Homework sets will be due at your quiz session. Late homeworks will not be accepted and will be assigned a grade of zero.

Exams: There will be 5 examenitos (little exams) scheduled every two to three weeks, and a final exam this semester. The lowest examenito score will be dropped and the balance will make-up 66% of the final grade. The final exam will consitute 17% of the final grade. You are expected to take the exams at the times and dates specified. The schedule for the examenitos and the final exam is given below.

Examenito 1: Monday, September 22, 1997

Examenito 2: Monday, October 6, 1997

Examenito 3: Monday, October 27, 1997

Examenito 4: Monday, November 10, 1997

Examenito 5: Monday, December 1, 1997

FINAL EXAM: Friday, December 12, 1997, 8:00 - 10:30 a.m.

Course Grade: Final letter grades will be assigned on a relative basis (a curve) and will be dependent solely on the total number of points accumulated (out of a possible 100 points) from the various portions of the course (exams [possible 83 points], quizzes [5 points], homeworks [5 points], and labs [7 points]) independent of the distribution between the segments. For example, a student who received 68 points (82%) from the exams, 0 points from the quizzes and homeworks, and 3 points (43%) from the labs would recieve the same final letter grade as a student who earned 54 points (65%) from exams, 5 points (100%) from quizzes, 5 points (100%) from homework, and 7 points (100%) from labs, since they both accumulated a total of 71 points out of a possible 100. However, a third student who also accumulated 71 points but did not complete six lab experiments and turn in six lab reports would be assigned a failing grade!

Integrity: Exams, quizzes, homework sets, and laboratory reports are to be entirely your own work using only the resources specified. When in doubt ask. Ethical behavior is fundamental in any professional discipline. Cheating or similar improper conduct in even the most minor way will result, at minimum, in a failing grade for the course. Further sanctions are likely in severe cases.

"Faith of the Engineer" from the Society of Professional Engineers

"I am an Engineer. In my profession I take deep pride, but without vainglory; to it I owe solemn obligations that I am eager to fulfill.

As an Engineer, I will participate in none but honest enterprises. To him that has engaged my service, as employer or client, I will give the utmost of performance and fidelity.

When needed, my skill and knowledge shall be given without reservation for the p ublic good. From special capacity springs the obligation to use it well in the service of humanity; and I accept the challenge which this implies.

Jealous of the high repute of my calling, I will strive to protect the interests and the good name of any engineering that I know to be deserving; but I will no t shrink, should duty dictate, from disclosing the truth regarding anyone that, by unscrupulous act, has shown himself unworthy of the profession.

Since the Stone Age, human progress has been conditioned by the genius of my pro fessional forbears. By them have been rendered usable to mankind nature's vast resources of material and energy. By them have been vitalized and turned to pra ctical account the principles of science and the revelations of technology. Except for this heritage of accumulated experience, my efforts would be feeble. I dedicate myself to the dissemination of engineering knowledge, and especially to the instruction of younger members of my profession an all its arts and traditions.

To my fellows I pledge, in the same full measure I ask of them, integrity and fair dealing, tolerance and respect, and devotion to the standards and the dignity of our profession, with the consciousness, always, that our special expertness carries with it the obligation to serve humanity with complete sincerity."

Supplemental Instruction: A supplemental instructor has been assigned to this course by the University Study Skills Center. A supplemental instructor is an undergraduate student who has previously taken a specific course and done well in it. The supplemental instructor's objective is to show current students how they can be more successful in a course. He/She organizes and leads study groups, helps with notetaking skills, and offers studying and exam taking tips. The supplemental instructor for MSE 130 this semester is Jeff Roggenbuck.
