摘要
文章描述了二次(回收)合金的主要问题，即由于铝废料重熔而产生的有害元素的存在，对AlSi7Mg0.6铸造合金的质量产生了负面影响。铁是二次Al- si合金中最有害的杂质，导致富β - fe (Al - 5fesi)金属间相的形成，其针状形状促进气孔和收缩等铸造缺陷的形成。适当的中和剂合金元素，如Mn，影响铁针状相的形成，导致形成危害较小的含Mn的α -富铁相。为了优化合金的形貌和性能，有必要研究各个合金元素对合金形貌和性能的影响。因此，本研究的重点是Mn添加对AlSi7Mg0.6二次合金中富铁金属间相和铸造缺陷的影响，从而评价其形态和分布。
The Effect of Manganese on Fe-Rich Intermetallic Phases in Progressive Secondary AlSi7Mg0.6 Alloy
: The contribution describes the major problem with the secondary (recycled) alloys as the presence of unwanted elements due to the remelting of Al-scrap negatively affecting the quality of AlSi7Mg0.6 cast alloy. Iron is the most harmful impurity in the secondary Al-Si alloys, leading to the formation of β -Fe-rich (Al 5 FeSi) intermetallic phases that promotes forming of casting defects such as porosity and shrinkage by its needle-like shape. Suitable neutralizer alloying elements, such as Mn, influence the formation of Fe-needle-like phases and lead to the formation of less harmful Mn-containing α -Fe-rich phases. To optimize the morphology and properties of alloys, it is necessary to study the effects of individual alloying elements. Therefore, this study is focused on the effect of Mn addition on Fe-rich intermetallic phases and casting defects, thus the evaluation of its shape and distribution in AlSi7Mg0.6 secondary alloy.
