Metals Through the Microscope

Editor's Note The accompanying article is the first of a series dealing with industrial applications of photography in all its phases. These articles will be designed to show our readers how the principles of photography can be utilized in a wide variety of industries and in locations ranging from the research laboratory, to the training school, and to the production line. Queries are invited from interested readers and suggestions for future articles in the series will be welcomed. Photography of Prepared Specimens Provides Permanent Records of Metallic Structures For Future Reference. Technique Can be Applied to Quality Control as Well as to the Search for New Alloys and New Treatments. Equipment for Photomicrography of Metals Has Many Other Uses
