    • A feedstock composition and a method of forming metal articles using powder metallurgy techniques comprise mixing metal or metal compounds powders and a novel aromatic binder system. The composition of the novel feedstock comprises an aromatic binder system and a metal powder. The aromatic binder system comprises an aromatic species and can further comprise lubricants, surfactants, and polymers as additives. The metal powder comprises elemental metals, metal compounds, and metal alloys, particularly for highly-­reactive metals. The method of forming metal articles comprises the steps of providing and mixing the metal powder and the aromatic binder system to produce a novel feedstock. The method further comprises processing the novel feedstock into a metal article using a powder metallurgy forming technique such as metal injection moulding. Metal articles formed using the present invention have an increase in carbon and oxygen contents each less than or equal to 0.2 wt% relative to the metal powder used to fabricate the article.
    • 原料组合物和使用粉末冶金技术形成金属制品的方法包括混合金属或金属化合物粉末和新型芳族粘合剂体系。 新型原料的组成包括芳族粘合剂体系和金属粉末。 芳族粘合剂体系包括芳族物质,并且还可以包含润滑剂,表面活性剂和作为添加剂的聚合物。 金属粉末包括元素金属,金属化合物和金属合金,特别是用于高反应性金属。 形成金属制品的方法包括提供和混合金属粉末和芳族粘合剂体系以产生新的原料的步骤。 该方法还包括使用粉末冶金成形技术如金属注射成型将新型原料加工成金属制品。 使用本发明形成的金属制品相对于用于制造制品的金属粉末,其碳含量和氧含量均小于或等于0.2重量%。
