    Abstract: A method for heating metal powder, e.g., iron powder, comprises irradiating the powder with microwaves. The powder may be coated with various materials to enhance the heating effects of the microwave. For example, the powder may be coated with a non-emissive material, such as a ceramic material. The powder may also be coated with a dipole material, such as water or plastic, or a dielectric material.

    Abstract: An improved metallurgical powder composition capable of being compacted at elevated temperatures is provided comprising an iron-based powder, an alloying powder, a high temperature compaction lubricant, and a binder. The selected binders of this invention permit the bonded powder composition to achieve increased compressibility in comparison to unbonded powder compositions while reducing dusting and segregation of the alloying powder.

    Abstract: Methods for preparing metallurgical powders containing an organic lubricant are provided. The powders are prepared by wetting a dry admixture of an iron-based powder, at least one alloying powder, and a first organic lubricant with an organic binding agent that is preferably dissolved or dispersed in a solvent. After removal of the solvent, the dried powder composition is admixed with a second organic lubricant.

    Abstract: Metallurgical powder compositions are provided which contain a metal powder in admixture with a solid, particulate polyether lubricant. The incorporation of the polyether lubricant enhances the green strength properties of compacted parts made from the powder compositions, and generally reduces the ejection forces required to remove the compacted part from the die cavity.

    Abstract: A method is provided for incorporating lubricant and a sintering aid into a metallurgical powder composition of iron-based powders. A particulate iron-based powder is contacted and wetted with solution of a metal salt of a fatty acid in an organic solvent. The solvent is removed to provide iron-based particles having a coating of the metal salt. The resulting self-lubricated powder composition can be compacted and sintered to produce a compact having superior strength properties.
