铝镁合金消失模铸造技术研究及应用新进展

New Advancements in Research and Application of Al Alloys and Mg Alloys by the Lost Foam Casting Process

阐述了铝镁合金消失模铸造技术的现状,重点介绍了铝镁合金消失模铸造在浇注充型、振动凝固、压力凝固、壳型铸造等技术研究方面的新进展。作者认为,消失模铸造铝镁合金,必须重点解决针孔、缩松等缺陷,提高液态合金的充型能力和铸件的力学性能。

This paper described the present situation of Al alloys and Mg alloys under lost foam casting （LFC） process and mainly introduced the new advancements on pouring and filling,vibration solidification,pressure solidification,shell casting,ete.The authors considered that the pinhole and shrinkage porosity casting defects must be emphatically solved for the Al alloy and Mg alloy of LFC,and the filling ability of molten alloy and mechanical properties of castings must also be improved.
