Notes:
The structure of intermetallic phases and planar defects in the as-cast and the solutiontreatedmicrostructures of a Mg-8Y-2Zn-0.6Zr (wt%) alloy are characterized using transmissionelectron microscopy. The alloy was produced by permanent mould casting and solution treated at500 °C. It is found that the intermetallic particles in the as-cast microstructure have a monoclinicstructure. An appreciable amount of intermetallic particles is still retained along grain boundariesafter solution treatments for up to 60 hrs. However, the structure of the retained intermetallicparticles changes gradually from monoclinic to hexagonal during the solution treatments. Someplanar defects are also detected in the as-cast and the solution-treated (1 hr) microstructures. Thesedefects have characteristic features of stacking faults
