• 10102 Effect of Cast Process on Mechanical Properties and Microstructure of Flame Resistance Magnesium Alloy

抄録

Effect of cooling rate and molten metal temperature on microstructure and mechanical properties of flame resistance magnesium alloy which prepared by antigravity cast process were investigated. Microstructure of antigravity casting material without water cooling is coarse grains (grain size was 850 μm) and Al-Ca compound to segregated in grain boundary. The Higher cooling rate promotes the formation of the compounds and voids in accordance with increases with internal and external temperature gap and differ from solidification rate of water-cooling steel mould. Due to the controlled cooling rate and molten metal temperatures, Mg phase was refined to 100 μm and Al-Ca compounds finely dispersed in the Mg phase. The as-cast alloy shows the ultimate tensile strength and elongation of 166 MPa and 8%, respectively.
