The research in this report was designed to extend the cryogenic embrittling technique to materials to improve the economics of conventional processing. Embrittling temperatures for various materials were determined, and a system was developed for chilling materials by indirect cooling rather than by dipping the materials directly into a refrigerant. A comparison of residence times for direct versus indirect chilling is presented.
