Average Course Rating

(4.12)

This course focuses on characterizing the microstructure and mechanical properties of structural materials that are commonly used in modern technology. A group of A1 alloys, Ti alloys, carbon and alloy steels, and composite materials that are found, for example, in actual bicycles will be selected for examination. Their microstructures will be studied using optical metallography, scanning electron microscopy, X-ray diffraction, and transmission electron microscopy. The mechanical properties of these same materials will be characterized using tension, compression, impact, and hardness tests. The critical ability to vary microstructure and therefore properties through mechanical and heat treatments will also be demonstrated and investigated in the above materials. Restricted to Materials Science & Engineering juniors only

The best aspect of this course was the hands-on approach to learning about material science. The lab experiments were interactive strengthened students’ knowledge of materials science. The worst aspects of the course included the class disorganization and lack of clarity on the professor’s part. Students were often unsure about how to complete labs and some of the lab equipment was either damaged or unavailable. The course would improve if there were clearer lab guidelines, new lab equipment, and an overal restructuring of the course. Prospective students should be prepared to spend lots of time on the

Professor: MATERIAL SCIENCE AND ENGINEERING

Students liked learning how to apply some of the concepts they’ve been learning in class, and thought that the labs were wel organized. They often found that the machines didn’t function properly, and that the lab reports took an overly long amount of time. Students suggested providing some deadlines to encourage lab reports getting done on a timelier basis. Other students would have liked switching up the lab groups occasional y to meet new people. Prospective students should be comfortable with mechanical properties of materials before taking this course. The course requires written lab reports, which will take some time but are not difficult to complete.

Students praised this course for having an engaged professor who chal enged students to learn through a variety of hands-on laboratory experiments. Perceived issues with the course varied. Some students found that the course was writing intensive, requiring they write up lab reports. Other students found that some labs could have unclear instructions. Suggestions for improvement of the course included a desire by some students for the course to provide students with new lab equipment as some students found the existing equipment somewhat faulty. Prospective students should know that students found that the course was an interactive experience and that it was important to begin working on lab reports early.
