Metallography Lab (P112)

RTEmagicC_metallography1  RTEmagicC_mountingarea

Students taking the Introduction to Materials course, working on design projects, or research use the Metallography lab to characterize metals and plastics. The lab contains all the equipment necessary to mount, polish, and examine material samples. There are four inverted microscopes; two with image capture. Failure analysis can be conducted on two stereo microscopes. The lab also contains the equipment necessary to prepare samples for electron microscopy. TEM samples can be prepared using the ultrasonic disk cutter, dimple grinder, and ion mill. SEM samples are usually prepared using the same procedures as optical microscopy samples.

Software

The computer in the metallography lab has Zeiss AxioVision for image capture and analysis.  ImageJ is also used to conduct measurements on microstructural features.

 

Resources for Students

There are several tutorials available for students to learn about making measurements with ImageJ here .
