Preparation of a novel Mg–Fe master alloy and its spheroidizing effect on graphite in ductile irons

Publication date: September 2018Source: Results in Physics, Volume 10Author(s): Tong Gao, Zengqiang Li, Junhao Fa, Xiangfa LiuAbstractSpheroidizing treatment is of crucial importance for producing ductile irons. A novel Mg–Fe master alloy has been achieved through the recycling procedure of Al–Si–Fe alloys in this paper. The alloy of Mg–50Fe–16Al–8Si with amounts of block–like Al2Fe3Si particles was synthesized by adding Al–14Si–2Fe alloy into Mg melt. It was found that the Mg–Fe master alloy exhibits attractive spheroidizing performance on a ductile iron Q10. This work confirms the significance for achieving Mg–Al and Mg–Fe alloys simultaneously through recycling Al–Si–Fe alloys.
