Engineering Materials - TCSU ENGR 110
Description
This course is a one-semester introductory course on the properties of engineering materials and how the properties relate to internal structure. Topics include: atomic structure and bonding; crystal structure; phases and phase diagrams; properties (mechanical, electrical, magnetic, optical) and structure of metals, polymers, ceramics and composites; mechanical deformation and fracture; taxonomy systems; corrosion and processing methods.
