Abstract:

Identifiers Pyroceram. New techniques and methods making it possible to study the rolling-fatigue process in Pyroceram were developed. A method for locating, orienting, and identifying specific areas to be viewed by the electron microscope is outlined. A replication technique is described which makes use of preshadowed silicon monoxide replicas deposited after the application of a releasing agent. A vibratory polishing technique was found to produce surfaces free of all evidences of fire-polishing, even when examined by electron microscopy. A satisfactory stain was found that reduces the glare of reflected light when examining Pyroceram specimens with the light microscope. Author
