Document Type and Number:
Japanese Patent JP2009045655
Kind Code:
A
Abstract:
To provide a method for casting an aluminum alloy foam for producing a lightweight aluminum alloy foam whose cell structure is homogeneous, and which is optimal for use as an impact energy absorbing member.
In an aluminum alloy foam b obtained by adding a thickener and a foaming agent to the molten metal (a) of an aluminum alloy, and performing stirring so as to cast the same, the casting temperature of the molten metal (a) upon the casting is controlled to +20 to +40C of the solidus temperature of the aluminum alloy, and further, the temperature of a mold 2 upon the casting is controlled to the liquidus temperature of the aluminum alloy or above and also to the casting temperature or above.
