Non Ferrous Alloys
This is a set of images which I made in 1962 that demonstrate metallurgical microstructures in nonferrous alloys.  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.
