摘要： A lightweight part and process and device of making the same, the lightweight part including an inner core including a metal foam. A dense core surface layer is metallically joined to the inner core. An outer wall includes an essentially pore-free cast metal layer that is at least one of positively engaged with the dense core surface layer and surrounding the inner core, and metallically joined to the dense core surface layer and surrounding the inner core. The process includes creating a core part by forming the dense core surface layer, forming the inner core of a metal foam, and metallically joining together the inner core and the dense core surface layer. The process further includes creating a finished part by positioning the core part in a casting mold, feeding a melt material into the casting mold, and allowing the melt material to solidify so as to form the outer wall. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

摘要： A novel lightweight gas metal composite is produced having isolated particle stabilized pores. A composite of a metal matrix, e.g. aluminum, and finely divided solid stabilizer particles, e.g. silicon carbide, is heated above the liquidus temperature of the metal matrix and this is mixed such that a vortex is formed. The molten composite is blanketed with a gas and during the vortex mixing. This gas is drawn into the melt to produce an expanded, viscous molten composite material containing pores which are very small, spherical-shaped and quite evenly distributed. The viscous molten composite material can be directly formed into a solid shaped product and is also capable of being remelted and formed by forming processes without destroying the integrity of the pores. The result is a lightweight expanded metal product capable of being formed into shapes to close dimensional tolerances.

摘要： A method is described for producing foamed metal in which gaseous bubbles are retained within a mass of molten metal during foaming. The method comprises heating a composite of a metal matrix and finely divided solid stabilizer particles above the liquidus temperature of the metal matrix, discharging gas bubbles into the molten metal composite below the surface thereof to thereby form a foamed melt on the surface of the molten metal composite and cooling the foamed melt thus formed below the solidus temperature of the melt to form a solid foamed metal having a plurality of closed cells.

摘要： A METHOD OF PRODUCING FOAMED METAL ALLOY PRODUCTS IS DISCLOSED INCLUDING THE STEPS OF HEATING THE ALLOY TO A TEMPERATURE BETWEEN ITS SOLIDUS TEMPERATURE AND ITS LIQUIDUS TEMPERATURE, MIXING INTO THE ALLOY A PARTICULATE MATERIAL WHICH DECOMPOSES TO RELEASE A SUBSTANTIAL AMOUNT OF GAS AT A TEMPERATURE ABOVE THE HEATING TEMPERATURE BUT BELOW THE LIQUIDUS TEMPERATURE, AND SOLIDIFYING AND WORKING THE ALLOY TO AN ARTICLE OF DESIRED SHAPE. THEREAFTER, TO EFFECT FOAMING THE ARTICLE IS REHEATED TO A TEMPERATURE ABOVE THE DECOMPOSITION TEMPERATURE OF THE FOAMING AGENT BUT BELOW THE LIQUIDUS TEMPERATURE TO CAUSE THE GENERATION OF GAS IN SITU AND RESULTING FOAMING. THE FOAMED ARTICLE IS THEN RAPIDLY COOLED TO STABILIZE THE FOAM.

摘要： A novel vessel and an improved method of casting batch liquid materials which solidify on cooling or standing utilizing said vessel; the method is especially advantageous for casting foamed metals whereby a composition containing molten metal and a suitable foaming agent is prepared in one or more upright, openended vessels provided with suitable gaskets and seated against the bottom of a mold. When the composition is ready to be cast, the vessels are vertically separated from the mold bottom so that only the lower ends of the vessels contact the composition as it quietly flows into the mold.
