Microstructures and Mechanical Properties of Rapidly Solidified Mg-Al-Zn-MM Alloys

Yeon-Wook Kim

材料科学技术（英文）

Mg-Al-Zn-MM (misch metal) alloy powders were manufactured by inert gas atomization and the characteristics of alloy powders were investigated. In spite of the low fluidity and easy oxidation of the magnesium melt, the spherical powder was made successfully with the improved three piece nozzle system...

Byoungho Kim , Jongjin Jeon , Yeongdo Park , Yongho Park , Ikmin Park

材料科学技术（英文）

The ageing behavior of Mg-xAl-Zn alloys with a variation of Al contents (x=3, 5, 7, 9 and 11 wt pct) were investigated. Solid solution treatment and artificial ageing were carried out at 693 and 493 K, respectively. After the solid solution treatment, β-Mg17Al12 was resolved to the α-Mg matrix in th...
