受电子工业部委托,东北轻合金加工厂研究所经过大量的试验研究,于今年研制成功了长孕育期铝合金,并于1985年4月11日至4月13日,由电子工业部、航天工业部和中国有色金属总公司共同对该合金进行了正式鉴定。众所周知,对热处理强化铝合金来说,固溶处理与时效之间的时间间隔一直是人们所重视和感兴趣的问题,因为当合金固溶处
Commissioned by the Ministry of Electronics Industry, Northeast Light Alloy Processing Factory Institute after a large number of experimental studies, this year successfully developed a long period of aluminum alloy, and in April 11, 1985 to April 13, the Ministry of Electronics Industry, aerospace Ministry of Industry and China Nonferrous Metals Corporation jointly conducted a formal identification of the alloy. It is well-known that the time interval between solution treatment and aging has always been a problem of great interest and interest for the heat treatment of the strengthened aluminum alloy because when the alloy solid solution point
