    摘要: Zirconium sponge can be chemically depassivated by treatment with hydrofluoric acid to improve the ability of molten magnesium/magnesium alloy to dissolve zirconium from the treated zirconium sponge and to form a melt containing substantially evenly distributed particles of zirconium. Optical micrographs showing the grain refining ability of pretreated sponge when added to pure magnesium at 680° C. All micrographs are of the same magnification. (a) Pure magnesium, (b) after adding 1 wt % sponge followed by 20 minutes manual stirring, and (c) after a further 10 minutes stirring.
