Atomic-scale characterization of the equilibrium β phase in Mg-Nd-Y alloy by means of HAADF-STEM.
The β phase in Mg-Nd-Y alloy, which forms during isothermal ageing, is proved to be Mg41Nd5by energy-dispersive X-ray spectroscopy (EDS) results as compositional evidence and by atomic-scaled high angle annular dark field-scanning transmission electron microscopy (HAADF-STEM) direct images from [001]β, [111¯]β, and [3¯11]β as structural evidence.
