Abstract Scope |
The increased use of aluminium scrap in the production of cast wheels is considered as a condition to satisfy the global trend for carbon footprint reduction. AlSi11 alloy is widely used in the production of wheels by LPDC-process. Typically, the iron content in this alloy does not exceed 0.19wt.%. The increase of the percentage of aluminum scrap leads to higher iron content in the melt. In the Al-Si alloys, iron tends to form the needle-like phase Al5FeSi, presence of which in the structure can significantly reduce the ductility of the alloy. The addition of manganese as an alloying element is used in practice in order to transform the needle-like phase Al5FeSi into a less harmful “Chinese srcipt”-like phase Al15(Fe, Mn)3Si2. The authors investigated the effect of various Fe /Mn content on the structure and mechanical properties of the AlSi11 LPDC-wheels to ensure the amount of Fe tolerated in the alloy. |
