Sand Cast Alloys
Microstructure of sand-cast AZ91D (Mg – 9% Al – 0.25% Mn – 0.7% Zn – 0.0008% Be) revealed (left) using the glycol etch and viewing with polarized light plus a sensitive tint filter; and (right) after etching with the acetic-glycol reagent and viewing in bright field illumination. The magnification bars are 100 and 50 μm, left and right, respectively. Note the mechanical twins at the surface.
