摘要
通过光学显微镜,在6 463铝合金铸棒生产实践基础上,研究了6 463铝合金在相同的熔铸工艺条件下,采用具有不同组织结构的Al-Si中间合金进行熔铸生产,原材料含硅相的遗传效应对铸造铝合金中Mg2Si相形态的影响,为优化6 463铝合金的熔铸生产,指导6 463铝合金的后续加工提供依据.结果表明,Al-Si中间合金的组织遗传性在熔铸过程中未得到破坏的情况下,会影响铸造铝合金中含硅相Mg2Si的形态与分布,为了避免粗大Mg2Si相对型材表面质量的影响,熔铸生产过程中应采用组织细小的Al-Si中间合金进行熔铸生产.
Through the optical microscope,based on the practice of 6 463 aluminium alloy production,with 6 463 aluminium alloy under the same casting process condition,the genetic effect of raw material containing silicon phase on casting of aluminium alloy on the morphology of Mg2Si phase in the aluminium alloy casting using Al-Si intermediate alloy with different structures in the casting production is studied.It provides the basis for optimization for 6 463 aluminium alloy casting production and guidance for subsequent processing of 6 463 aluminium alloy.The results show that the organization of hereditary Al-Si intermediate alloy which has not been damaged in the casting process,will affect the casting pattern and distribution of aluminum alloy containing silicon phase Mg2Si.In order to avoid the effect of surface quality of coarse Mg2Si relative profiles,Al-Si intermediate alloy of fine microstructure should be used in casting production.
