采用SEM
EDS
TEM等试验方法研究了3004铝锰合金的铸态组织及性能.结果表明:细晶铝锭用于熔炼3004铝锰合金时
其铸态综合力学性能与A l-5Ti-1B中间合金、Al-10Ti中间合金细化的试样差别不大.3004铝锰合金在未均匀化时
其析出相为粗大的骨骼状共晶组织;均匀化后析出相在一定程度上球化
且晶内析出细小弥散的析出相
同时粗大的M g2S i也溶于铝基体中
这均使均匀化后的合金塑性提高.3004铝锰合金中骨骼状析出相、块状析出相、条状或针状析出相含有较高的Fe
Mn
Si元素
析出相中没有M g的偏聚
镁在合金中分布均匀.
The as-cast microstructures of 3004 aluminum alloys were studied with the aid of SEM
EDS and TEM
etc.The results show that the mechanical properties of 3004 aluminum alloys adding Ti with grain-refining aluminum ingots(GRAI)
Al-5Ti-1B and Al-10Ti master alloys are almost the same.3004 aluminum alloys in as-cast state show skeleton-like eutectic structure.After the homogenization process
precipitated phases spheroidize to some extent
and fine disperse phases appear in grains
at the same time
the coarse Mg2Si phases dissolve in α(Al).The results of EDS analysis indicate that the acicular
skeleton-like
blocky
banding-like precipitate phases contain higher Fe
Mn and Si
but no Mg segregation.Homogeneous distributions of Mg are observed in the matrix.
