INTRODUCTION
- Lesson 1
This is the first lesson in a set of images
demonstrating metallurgical
microstructures. These microstructures are shown to be sensitive
to the processing and environmental history of each macrosopic
specimen. The color photomicrographs were prepared by me from a
set of
specimens of known history collected by the staff of M.I.T. in the
years prior to 1959. |
| 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. |
