摘要
为了提高航空铝青铜QAl10-4-4材料的机械加工及使用性能,对热轧状态铝青铜QAl10-4-4进行热处理工艺试验,通过硬度检测和金相组织分析,优化了工艺参数。当布氏硬度要求250~300HBS时,采用900℃固溶和430~530℃时效,可获得最佳的力学性能和金相组织。为制定铝青铜QAl10-4-4的热处理工艺提供了重要依据。
In order to improve mechanical processing and usability of aluminum bronze QAl10-4-4,the heat treatment technical examinations were carried out for QAl10-4-4 as hot-rolling. Technical parameters were optimized by hardness testing and metallographic structure analysis. When the requirement of hardness was 250 to 300 HBS,the excellent mechanic performance and metallographic structure were obtained with solid solution at 900 ℃ and aging at 430 to 530 ℃,which provide an important basis for making the heat treatment technology of QAl10-4-4.
