摘要： Methods and devices are disclosed for creating a multiple alloy composite structure by forming a three-dimensional arrangement of a first alloy composition in which the three-dimensional arrangement has a substantially open and continuous porosity. The three-dimensional arrangement of the first alloy composition is infused with at least a second alloy composition, where the second alloy composition comprises a shape memory alloy. The three-dimensional arrangement is consolidated into a fully dense solid structure, and the original shape of the second alloy composition is set for reversible transformation. Strain is applied to the fully dense solid structure, which is treated with heat so that the shape memory alloy composition becomes memory activated to recover the original shape. An interwoven composite of the first alloy composition and the memory-activated second alloy composition is thereby formed in the multiple alloy composite structure.

摘要： A method for producing precision shapes which includes the consolidation of powder metal preforms into a shaped porous preform. A first coating is applied to the preform, this first coating being porous while providing a diffusion barrier. A second coating which is also initially porous is then applied and the coated preform can then be degasified by subjecting the preform to a vacuum, particularly at elevated temperatures. The coated preform is then heated under vacuum to a temperature such that the second coating is densified to the extent that it becomes non-porous. Finally, the preform is subjected to a hot isostatic pressing operation whereby formation of high integrity, fully dense metal shape results.

摘要： A container made of a porous material and coated with precious metal nanoparticles is disclosed. The method of making it includes: adding precious metal nanoparticles and intermedium particles to a solution; maintaining the solution at a first temperature; heating a container body made of a porous material at a second temperature; and immersing the container body in the solution wherein the temperature difference between the first temperature and the second temperature causes the precious metal nanoparticles and intermedium particles to permeate into the pores of the container body. The resultant container has precious metal nanoparticles not only attached to its surface but also within its pores.

摘要： In the method of invention, the formability is imparted to the slurry of a metal or ceramic powder by employing a porous mold and removing the dispersion medium through the evaporation or thermal decomposition thereof, or by using a silazane oil as the dispersion medium and curing it by heating. Since the phase change usually accompanying volume change does not occur in the dispersion medium, strain and deformation rarely occur in the molded body. As result, the sintered body obtained has high dimensional accuracy.

摘要： A method for the manufacture of objects from powdered material by isostatic or pseudo-isostatic pressing. A porous body (10), with open pores in contact with the external surface(s), is preformed from a powdered material, whereupon at least one layer (11, 12) of a powdered material is applied onto the external surface of the preformed porous body by dipping. The preformed porous body is covered with a casing (13) of glass, or a material which forms glass upon heating, arranged outside the intermediate layer (12). The casing is made impenetrable to the pressure medium by heating, whereupon the preformed body is compacted to an essentially dense body. The pore system of the preformed porous body is evacuated by applying a sub-atmospheric pressure by means of at least one suction cup (21) which is applied on the external surface to be coated in connection with and during the dipping of the body in a slurry (20) of powdered materials included in the layer (11, 12).

摘要： A preformed body (12) from powder material of metallic and nonmetallic compositions and combinations thereof, is consolidated to form a densified compact (12") of a predetermined density. An outer container mass (20), capable of fluidity in response to predetermined forces and temperatures and which is porous to gases at lesser temperatures and forces than said predetermined force and temperature, surrounds an internal medium (22). The internal medium encapsulates the preformed body (12) within the container mass (20) and is capable of melting at the lesser temperatures to form a liquid barrier to gas flow therethrough. The internal medium (22) is capable of rapid hermetic sealing during the early stages of preheat. External pressure is applied by a pot die (16) and ram (14) to the entire exterior of the container mass (20) to cause the predetermined densification of the preformed body (12) by hydrostatic pressure.

摘要： A method for manufacturing an object of silicon nitride by isostatic pressing of a preformed body of silicon nitride powder utilizing a pressure medium at a temperature sufficiently high to sinter the silicon nitride. The preformed body is subjected to a degassing operation before isostatic pressing. An inner porous layer of a first material and then an outer porous layer of a second material are applied on the preformed powder body. The inner porous layer is transformable, at a temperature below the sintering temperature for silicon nitride, into a pressure medium impermeable layer. The outer porous layer is also transformable into a pressure medium impermeable layer, but at a temperature which is lower than the temperature when the inner porous layer is converted into its pressure medium impermeable form. Thus, the preformed body is first subjected to a degassing and to a heating to the temperature for transforming the outer porous layer into a pressure medium impermeable layer while the inner porous layer is maintained in a porous form. Thereafter the preformed body and the surrounding layers are heated further to the temperature for converting the inner porous layer into its pressure medium impermeable form while a pressure greater than the gas pressure inside the layers is maintained on the outside of the layers. The isostatic pressing of the preformed object is then carried out.
摘要翻译： 通过使用压力介质在足够高的温度下均匀压制氮化硅粉末预制体来烧结氮化硅的方法来制造氮化硅的目的。 在等静压之前对预成型体进行脱气操作。 将第一材料的内部多孔层，然后将第二材料的外部多孔层施加到预成型的粉末体上。 在低于氮化硅的烧结温度的温度下，内部多孔层可变形成压力介质不渗透层。 外部多孔层也可以转化成压力介质不渗透层，但是在比内部多孔层转化为其不可渗透压力介质时的温度低的温度下。 因此，预先形成的主体首先进行脱气和加热至将外部多孔层转化为压力介质不渗透层的温度，同时内部多孔层保持多孔形式。 此后，将预成型体和周围层进一步加热到将内部多孔层转化成其不可渗透压力介质的温度，同时在该层的外侧保持大于层内的气体压力的压力。 然后执行预成型物体的等静压。
