    • The present invention relates to improved metallurgical powder compositions, methods for the preparation of those compositions, and methods for using those compositions to make compacted parts. The metallurgical powder compositions comprise a base metal powder, such as an iron-based or nickel-based powder, to which is added or blended an organometallic lubricant. Organometallic lubricants are monomers or polymers having a metal-carbon bond or metalloid-carbon bond on the polymer backbone, which degrade into physical property enhancing compounds upon heating. The metallurgical powder compositions can also comprise small amounts of other commonly used alloying powders, binding agents, and lubricants.
    • 本发明涉及改进的冶金粉末组合物,制备这些组合物的方法以及使用这些组合物制造压实部件的方法。 冶金粉末组合物包含添加或混合有机金属润滑剂的基底金属粉末,例如铁基或镍基粉末。 有机金属润滑剂是在聚合物主链上具有金属 - 碳键或准金属 - 碳键的单体或聚合物,其在加热时降解为物理性质增强化合物。 冶金粉末组合物还可以包含少量其他常用的合金粉末,粘合剂和润滑剂。
