Scanning electron micrographs showing the existence of white cuboid particles with a very high Dy content in Mg-20 wt% Dy samples using sample preparation method (i). (a) As cast; note the white particles indicated by arrows. (b) Solutionized at 793 K for 24 h then water quenched. (c) Solutionized at 793 K for 24 h followed by water quenching and then ageing at 523 K for 16 h.  [article HTML]
