Control of Residual Stress: Cryogenic Stress Relieving
{"Image DocumentName": "Control of Residual Stress: Cryogenic Stress Relieving", "Image ImageDescription": "Takes various structures at very slow rate down from room temperature to 300\u00ba below 0\u00baF by exposing them to liquid nitrogen vapors. Done at 1\u00baF per minute. Allowed to soak at holding temperature for 24 to 36 hours. Molecules in structure get closer together. At end of holding period structure slowly warmed back up to room temperature. Rate of 1\u00baF per minute.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
