Course Description
This course provides an introduction to materials processing science, with an emphasis on heat transfer, chemical diffusion, and fluid flow. We use an engineering approach to analyze industrial-scale processes, with the goal of identifying and understanding physical limitations on scale and speed, and cover materials of all classes, including metals, polymers, electronic materials, and ceramics. Specific processes, such as melt-processing of metals and polymers, deposition technologies (liquid, vapor, and vacuum), colloid and slurry processing, viscous shape forming, and powder consolidation are considered.
Grading Components
| ACTIVITIES | DESCRIPTIONS | PERCENTAGES |
|---|---|---|
| 2 Tests | There will be two tests focused on concepts, which will take place in class. | 40% |
| Final Exam | There will be a comprehensive final at the end of the course. | 35% |
| Homework | 6 problem sets are planned, each with about 1.5 weeks between distribution and due date. These will likely be more mathematical than conceptual. | 25% |
Note that for all assignments and exams, every problem will be equally weighted (5 points).
