摘要： The porous material of the present invention is produced by heating a dry powder mixture, containing mainly an organic solid binder and inorganic particles. The mixture is foamed while the organic binder is melted. Foaming comes from a foaming agent in the powder mixture. The solid foamed structure comprising inorganic particles embedded in an organic binder is then heated to eliminate the organic binder and finally to sinter the remaining inorganic tri-dimensional network into a rigid structure having interconnected porosity.

摘要： Near-net-shape soft magnetic components can be produced from iron powder lubricant compositions using powder metallurgy techniques. The resulting components have isotropic magnetic and thermal properties and may be shaped into complex geometry using conventional compaction techniques. A non-coated ferromagnetic powder is mixed with a lubricant and compacted. After compaction, the components are thermally treated at a moderate temperature to burn out the lubricant, relieve the stresses induced during pressing and reduce the hysteresis losses. Depending on the application, the properties of the material may be tailored by varying the content and type of the lubricant and the thermal treatment conditions.

摘要： A binder for metallurgical powder compositions for powder metallurgy (P/M) applications includes styrene/maleic anhydride copolymers and their derivatives. Addition of such binders has improved resistance to dusting, and has improved flow properties of the compositions, even in high relative humidity environments. The compositions can be compacted either at cold or warm temperatures. A mechanical strength of a sintered product containing the binder-treated mix is similar to that of sintered products without the binder.

摘要： Aluminum powder compositions intended for powder metallurgy applications are provided. The powder compositions contain aluminum and aluminum alloys or blends made from elemental powders, admixed with a polyethylene lubricant. The polyethylene admixture eases the compaction of powders and the ejection of parts. As compared to other conventional admixed lubricants used for Al powder metallurgy applications, polyethylene allows to obtain parts with higher green and sintered strengths. Proper delubrication prior to sintering is of importance.
