INTRODUCTION - Lesson 3This is the third lesson in a set of images prepared by me that demonstrate metallurgical microstructures found in the M.I.T. specimen collection. These microstructures are more complex than those shown in the first two groups. Compare them carefully, and use the phase diagrams to interpret the squence of treatments or phase changes.
|Allow plenty of
time to study and to take good notes about each specimen. About
two hours per lesson would be appropriate. You will be expected
to interpret some of these specimens during the final
examination. Feel free to use the Internet to find additional
information about the alloys and applications mentioned here.
