Microstructure and mechanical properties of Mg-0.6Si-xZn alloys (x = 0-1.6 wt%) were investigated to reveal the modification effect of Zn on the morphology of eutectic Mg 2 Si. It was found 0.5-1.3 wt% Zn effectively modified the morphology of eutectic Mg 2 Si from laminated structure to fine fiber,

Mg-Sn based alloys have great potential for high temperature applications because of the formation of the thermally stable Mg 2 Sn phase in the as-cast condition. In the present investigation, for further enhancement of the mechanical properties, 0.7, 1.4 and 2 wt.% of Ca was added to the base Mg-5%
## Abstract Corrosion properties of three different SnβAg lead free solder alloys have been investigated in 0.3 wt% Na~2~SO~4~ solution as corrosive environment. As cast solder alloy was analyzed by Xβray diffraction (XRD) and scanning electron microscopy (SEM). Volume fractions of the Ag~3~Sn in t
