摘要
The fluidity is one of the most important properties for cast alloy. The quality of castings is influenced by the fluidity of liquid metal. especially under gravity castina conditions. In this paper, the factors affecting the fluidity of cast magnesium alloy have been studied by vacuum suction method. The experimental data show that the relationship between the fluidity of magnesium alloy and pouring temperature can be described as an exponential damping curve. The length of freezing range, which varies with the content of alloy elements, such as Al, Zn, Mn and Ce, influences the fluidity of magnesium alloy. In Mg-Al-Zn-Mn-Ce alloy system inter-metallic phases precipitated during pouring reduce the fluidity of magnesium alloy. (c) 2006 Elsevier B.V. All rights reserved.
