    摘要： A method of forming a material includes the steps of: vibrating a molten material at an ultrasonic frequency while cooling the material to a semi-solid state to form non-dendritic grains therein; forming the semi-solid material into a desired shape; and cooling the material to a solid state. The method makes semi-solid castings directly from molten materials (usually a metal), produces grain size usually in the range of smaller than 50 μm, and can be easily retrofitted into existing conventional forming machine.

    摘要： A method for producing a ductile cast iron product, wherein the cast iron product contains sulfur in an amount of 0.009 to 0.015 wt % and magnesium in an amount of 0.035 to 0.050 wt %, and wherein a dried sand is used for a mold. The method can be suitably employed for producing, at a low cost, a ductile cast iron product which is not chilled and has a ferritic structure, and thus is soft and exhibits great ductility even when it is a thin product. The present invention has been completed based on the finding that the combination of the increase in a certain degree of the content of sulfur, which has been considered to be a substance interfering with the formation of spherical graphite, with the lowering of the rate of cooling allows the production of a ductile cast iron product which is not chilled and has a ferritic structure, and thus is soft and exhibits great ductility even when it is a thin product.

    摘要： A method and apparatus is provided for producing a porous metal. The method broadly includes the steps of first, providing a molten metal and second, introducing a gas into said molten metal. The method then includes spray casting the molten metal containing the gas onto a surface thereby producing the porous metal. The method further provides for controlling the amount and size of the porosity contained within the porous metal by controlling the parameters at which the gas is introduced into the molten metal, as well as, controlling the parameters surrounding the spray casting of the molten metal. Additionally, the method also provides for producing a porous metal having either an isolated or interconnected pore structure. The present invention also provides for a porous metal product, as well as a porous aluminum alloy product, made by the described method. The apparatus includes a means for containing the molten metal wherein the containing means has a discharge end. A means for introducing a gas into the containing means is also provided. The apparatus further includes molten metal discharge means positioned adjacent the discharge end of the containing means for atomizing the molten metal that is discharged from the discharge end into metal droplets, and a substrate on which the metal droplets are deposited in order to form the porous metal.
