OFFICE HOURS: TTh 1:00-3:30pm, by appointment all other times

Note: Part or all of the office hours might be in the classroom (CAT-305) as student questions warrant.


Introduces the foundations of the chemistry and physics of materials used in engineering applications. Develops the relationship between the atomic and molecular structure of materials and the macroscopic properties and performance of engineering material. In particular includes thorough discussion of the chemical and physical properties of metals, ceramics, polymers, semiconductors, superconductors, and nanomaterials.

In the Engineering program at Prince George's Community College, for all credit course, students are expected to spend a minimum of 45 combined hours of instructional time and related coursework time per credit hour. This course is a 3 credit course with a portion of that credit being laboratory. This course achieves the minimum of 135 hours of instructional time by requiring 18.75 hours of instructional time, 18.75 hours of laboratory time and 97.5 hours of student work outside of instructional time. Minimum outside instructional time assumes the student is aiming for a C, not an A.


Upon successful completion of the course a student will be able to

  1. Identify crystalline structure and how they effect the properties of solids especially with regard to strengthening, fatigue, and failure.

  2. Identify experimental procedures to determine material characterization.

  3. Understand and identify the differences in properties and structures of metals, special alloys (such as biometals), thermoplastics, ceramics, special composite materials, semiconductors, nanomaterials, glasses, and superconductors.

  4. Perform analysis crucial in the design of structures in engineering problems using relationships derived from the structural properties of the engineering material.

  5. Predict the behavior of materials using phase diagrams (binary, ternary).

  6. Show the ability to self-teach oneself from the foundational material presented in the course.

  1. Bound Laboratory book. Pages are to remain in the book and are NEVER to be torn out.

  2. Pens, Pencils, Textbooks, Eraser, Straight edge, Paper, and Calculator are required for every class.


As with any class an amount of time at least equivalent to two times the credit hours is expected to be performed for homework and labs. Please allot sufficient time for homework.

Homework will be assigned each week including the first week.


Evaluation of student performance is to be based on:

  1. Unannounced quizzes and assigned homework will account for approximately 25% of the semester grade. Homework consists of problem sets.

  2. Two (mid-term and final) comprehensive in-class test on materials science will account for approximately 25% of the semester grade each.

  3. A multi-page essay on an aspect of materials science will account for approximately 25% of the semester grade. This essay is to be an original work. No sharing of work.


Students are expected to attend and participate in class activities. Students who either never attended the class or who ceased attendance during the first 20 percent of the course will be assigned a "Q" grade by the instructor. The Q grade is a final grade and will not be replaced with a different grade at a later time.

Faculty are required to report the date of last attendance for each student receiving Q or F grade(s) in order for the college to report this date to a variety of federal agencies as mandated. The date of last attendance is considered the date of the student's termination from the course, regardless of the date of grade submission. Early termination from a course may result in reduction in student loans and financial aid (e.g., Pell, VA benefits) and may require the student to reimburse funds to the funding agency.


  1. Homework is due at the start of class (or before) except for in-class projects.

  2. Laboratory work is to be submitted in appropriate binders follow any standard laboratory format (this will be reviewed in class).

  3. Make-up homework, quizzes, and/or tests are up to the discretion of the teacher (excused absences only). No makeup will be possible for laboratory work, sufficient time should be available to recover if an absence is necessary.


New topics are to be covered each week and include but are not limited to the following subjects. This outline is subject to change.

Week 1 Introduction to materials science

Week 2 Atomic Structure and Bonding

Week 3 Crystal and Amorphous Structure in Materials

Week 4 Solidification and Crystalline Imperfections

Week 5 Thermally Activated Processes and Diffusion in Solids

Week 6 Mechanical Properties of Metals (Stress, Strain, Deformation)

Week 7 Mechanical Properties of Metals (Fracture and Fatigue)

Week 8 Phase Diagrams

Week 9 Engineering Alloys

Week 10 Polymeric Materials

Week 11 Ceramics

Week 12 Composite Materials

Week 13 Electrical Properties of Materials(+Nanoelectronics)

Week 14 Nanotechnology

Week 15 Optical Properties and Superconductive Materials

Reading assignmentsare as follows: For class it is expected that an article or book on engineering that is appropriately technical is to be read each week.

Quizzes will all be unannounced so be prepared.

Tests will be announced a week before and will depend on our progress in the classroom.


  1. Food and drink in limited quantities (snacks, not meals) are permitted in restricted areas (not near electronics or computers) and will be revoked if proper cleanliness is found wanting.

  2. Cell phones must be in vibrate mode and are only to be answered for emergencies (step outside please).

  3. Common courtesy is to apply at all times.
