Abstract (en)
[origin: WO2007092203A2] A method for forming a semi-solid metal or alloy having non-dendritic grain structures using gas bubbles, includes heating metal or alloy above a melting temperature thereof to provide liquid metal or alloy, flowing gas bubbles through at least one solid medium inserted into or accommodates therein the liquid metal or alloy thereby cooling the liquid metal or alloy to a temperature below the melting temperature thereof while agitating the liquid metal or alloy with the gas bobbles and forming solid fractions therein, and stopping flowing the gas bubbles therethrough when the solid fraction of solid reaches a range of 0.01-0.5 by weight thereby providing the semisolid metal or alloy having non-dendritic grain structures.
