| Abstract: | Relationship between temperature and phase tran sition,cold minification of hypo eutectoid steel has been analysied.Cold minification of medium carbon steel forgings cooled from that of an austenite zone to normal temperature has been processed statistically to regression equation which can accurately determine cold minification of hot forgings. |
