摘要: 本文通过采用硬度测量,差热分析及透射电镜综合研究了Al2O3p/6061复合材料在时效过程中的析出变化。结果表明,在Al2O3p/6061时效过程中,峰时效的主要强化相是β'相,并且以160℃,8小时时效的效果为最佳。Abstract: In this paper,the process of aging precipitation in the Al2O3/6061 compositestry was investigated.Hardness,differential scanning calorimetry (DSC),and transmission electron microscopy were employed.Results show that the main precipitation phase of peak hardness is β'-phase,and it is suggested that solution treated at 530℃,aging at 160℃ for 8 hours is an ideal aging technique.
