EGR 376: Material Science and Engineering Lecture

EGR 376: Material Science and Engineering Lecture

Term: Spring 2023

Instructor: Mike Kinsinger

Description of course: Periods in human history have been defined by advancements in new materials. Discoveries in Materials Science have lead the way to new technologies in every engineering discipline and continue to be at the forefront of developing fields such as biomaterials and nanotechnology. This course will provide a broad introduction into the world of Materials Science with a special emphasis on the relationship between the composition, processing, structure, and properties of metals, ceramics, polymers, and composites. Prerequisites: EGR 270 and EGR 290.

  • #1

Scanning Electron Micrographs (#1-5) of various materials. All samples prepared and images acquired by students in this course.

#1: SEM and EDS analysis of solder composed of tin (Sn). Depending on the temperature used when applying the solder, the quality of the joint will vary.

#2: SEM of a fractured surface of 2H pencil lead. Comparing the morphology of different hardness of pencil lead.

#3: SEM of a broken PLA, material used in 3D printers. Over time PLA absorbs humidity and the quality of the print deteriorates.

#4: SEM of small droplets of polymer solution on glass disks that dried into membranes. Morphology of membranes possibly changes when prepared under different conditions.

#5: TEM of gold nanoparticles.  Gold nanoparticles with different theoretical sizes are prepared and measured using the images from the TEM.
