What is MSE? The MSE major at OSU

1. Materials Science and Engineering Megan Daniels Undergraduate Advisor 477 Watts Hall 292-3145 [email_address] mse . osu . edu

5. Another way to look at MSE Materials Engineers work on the structure-properties-processing-performance relationships of materials. The “ Materials Tetrahedron” Performance Properties Synthesis/ Processing Structure / Composition

6. Metallic Materials Metals are strong, shiny, and good conductors of heat and electricity. They dominated the field of MSE in the 20th century. The focus of metals research is changing to encompass better processing techniques and newer high-tech metals.

7. Ceramic Materials Ceramics serve many purposes because they are lightweight and resistant to high temperatures.

8. Semiconductors Semiconductors are key to the development of all Electronic Materials.

9. Polymeric Materials Polymers are easy and cheap to produce, and can have surprising strength. Limited by their instability at high temperatures.

10. Biomaterials Biomaterials are used for implants and the development of materials that can be placed in the body.

11. Composite Materials Composites consist of more than one material type. Fiberglass, a combination of glass and a polymer, is an example. Concrete and plywood are other familiar composites. Many new combinations include carbon nanotubes and ceramic fibers in metal or polymer matrix.

12. What do Materials Engineers do? • Design materials. • Design manufacturing processes. • Recommend materials based on properties, processing cost, and marketability. • Help define product and the operating conditions. • Troubleshoot and solve problems with materials selection, production, and service. • Forensic engineering: failure analysis.
