摘要
分析了亚共析钢的相变和冷缩率与温度的关系。对中碳钢从奥氏体区冷却到常温时锻件的冷缩率进行了数学统计,回归成数学公式,较精确地确定了热锻件冷缩率。
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.
