摘要： A powder metal mixture is disclosed that provides improved mechanical properties for parts made from powder metal, such as cam caps. The powder metal mixture, upon sintering, forms an S phase intermetallic in the Al—Cu—Mg alloy system. The S phase is present in a concentration that results in an enhanced response to cold work strengthening of the powder metal part. Further, by minor adjustments to certain alloy elements, such as tin, the tensile properties of the resultant part may be adjusted.
摘要翻译： 公开了一种粉末金属混合物，其为由粉末金属制成的部件（例如凸轮盖）提供改进的机械性能。 粉末金属混合物在烧结后在Al-Cu-Mg合金体系中形成S相金属间化合物。 S相存在的浓度导致对粉末金属部件的冷加工强化的反应增强。 此外，通过对诸如锡的某些合金元素进行微调，可以调节所得部件的拉伸性能。
