摘要： A process for making a porous mass of a metal of iron- or titanium-group comprises steps of forming a sinter of solvent-soluble particles, pressing in a molten metal of the iron- or titanium- group into open interstices in the sinter, and eluting the particles from the composite of the sinter and metal. Solvent-soluble magnesia particles whose surface is either covered or not with a film of boric anhydride or solvent-soluble calcia particles whose surface is either covered or not with film of calcium chloride are sintered and machined into the desired shape. The formed sinter is put in a case of a heat-insulating material that can withstand the melting temperature of a metal of iron- or titanium-group. After being heated to a given temperature together with the case, the sinter is immediately put in a metal mold where a molten metal of iron- or titanium-group is pressed into open interstices in the sinter. Then, only the particles are eluted from the sinter-metal composite by a solvent.

摘要： A foamed metal which has an apparent specific gravity of from 0.2 to 0.8 and comprises an aggregate of polygonal closed cells of from 2 to 10 mm in average diameter. The foamed metal is not only light in weight, free of directionality and structurally strong but also excellent in sound-absorbing and electromagnetic shielding properties, and is useful as constructional, structural or functional material. A method for producing the foamed material comprises adding calcium as a thickening agent to molten aluminum or alloy thereof in an amount of from 0.2 to 8% by weight, followed by agitating to adjust the viscosity of the melet, then adding from 1 to 3% by weight of powdered titanium hydride as a foaming agent to the melt, and agitating the melt to effect foaming.

摘要： The invention provides an improved method for the preparation of a porous ongy body of a metal or alloy having an open cell structure. The basic principle of the method is the pressurized casting of a melt of the metal or alloy with a preheated powder compact of an inorganic compound soluble in a solvent to fill up the pores and dissolving away the inorganic compound with a solvent after solidification of the melt. The improvement comprises forming interconnections bridging the particles in the powder compact and, different from conventional methods in which the preheating temperature is higher than the solidification temperature of the melt, preheating the powder compact at a temperature lower than the solidification temperature of the melt but higher than a critical preheating temperature defined as a function of the solidification temperature of the melt, latent heat of solidification of the melt, density of the metal or alloy, volume fraction of the inorganic compound in the powder compact under casting, specific heat of the inorganic compound and true density of the inorganic compound.
摘要翻译：本发明提供了一种制备具有开孔结构的金属或合金的多孔海绵体的改进方法。该方法的基本原理是将金属或合金的熔体用预先熔化的可溶于溶剂的无机化合物的粉末压块进行加压铸造以填充孔隙，并在熔体固化后用溶剂溶解掉无机化合物。改进之处在于形成桥接粉末压块中的颗粒的互连，并且与预热温度高于熔体凝固温度的常规方法不同，在低于熔体固化温度的温度下预热粉体，比作为熔体固化温度函数的临界预热温度，熔体固化潜热，金属或合金的密度，铸造中的粉末压坯中的无机化合物的体积分数，无机的比热无机化合物的化合物和真密度。
