摘要
用正交试验的方法 ,对铍青铜形变时效工艺进行了优选。试验表明 ,控制冷变形度、时效温度和时效时间 ,可获得高的硬度 ,优化后的铍青铜形变时效工艺为 :37%冷变形 + 2 90℃× 2h。
The optimum selection of deformation aging process of beryllium bronze was tested with orthogonal experimentation.The results show that treated with a suitable extent of cold deformation,aging temperature and aging time,the beryllium bronze could gain high hardness.The optimum deformation aging process of the beryllium bronze were given which is 37% of cold deformation then aging at 290℃ for 2h.
