摘　　要：通过X射线、SEM和TEM分析,研究了电解低钛铝合金和熔配加钛铝合金在铸造状态、轧制状态和热处理状态的组织。在6009铝合金中,球形Mg2Si是主要强化相,熔配加钛合金时效过程调幅分解明显。在电解低钛铝合金中,球形Mg2Si分布更为弥散、均匀。结果表明:电解低钛铝合金的性能优于熔配加钛铝合金。The microstructure of electrolytic low-titanium alloy and master alloy in three different techniques including the cast, rolling and heat treatment was studied by XRD,SEM and TEM. In 6009 alloys, spherical Mg2Si is the dominant strengthing phase. Spinodal transformation is obviously occurred during the aging in master alloy, spherical Mg2Si is more dispersive. The result shows the property of electrolytic low-titanium alloy is better than master alloy.
