INTRODUCTION - Lesson 2
This is the second lesson in a set of images
demonstrating
metallurgical
microstructures. These microstructures include more complex
alloys
and several examples of failures. 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. |
