    摘要： A compaction tool assembly is provided that uses multiple die cavities and a single compaction stroke for simultaneously forming multiple discrete powdered metal components. The tooling includes a plurality of punches and corresponding die cavities, and a single compaction stroke operates the punches to compact powdered metal contained by the die cavities to form the components. Preferably the punch pairs are arranged concentrically to balance compaction forces and die stresses.

    摘要： A method for making a high density powdered metal article is provided. The composition consists of iron based powder, lubricant, graphite and ferro alloy additions. The composition is compacted in rigid tools at ambient temperature, sintered at high temperature and then formed in rigid tools at 40 to 90 tons per square inch to a density greater than 94% of theoretical. The high density article is then annealed. The final article demonstrates remarkable mechanical properties which are atypical of powdered metal components and approach those of wrought steel.

    摘要： A method for making a high density powdered metal article is provided. In one embodiment, the composition consists of iron based powder, lubricant, graphite and ferro alloy additions. Satisfactory results may also be achieved by using fully prealloyed grades of metal powders, substantially pure powder blends, fully prealloyed powder blends, partially prealloyed powder blends and powder blends containing ferro alloys. The composition is compacted in rigid tools at ambient temperature, sintering at high temperature greater than 1100.degree. C. and then formed in rigid tools at 40 to 90 tons per square inch to a density greater than 94% of theoretical. The high density article is then annealed. The final article demonstrates remarkable mechanical properties which are atypical of powdered metal components and approach those of wrought steel.

    摘要： A manufacturing method is provided for the production of high density, high carbon, sintered powder metal steels. The composition consists of iron based powder, graphite, lubricant, and possibly at least one alloying element from the group of chromium, copper, manganese, molybdenum, nickel, niobium or vanadium. The composition is compacted in rigid tools, sintered and during cooling an isothermal or slow cooling treatment is introduced between 650.degree. C. and 750.degree. C. The isothermal or slow cooling treatment may alternatively be applied during a heat treatment cycle that is carried out after a conventional sintering cycle. The material processed as described may then be formed to high density. Forming to high density is not practical with high carbon materials that have been processed by conventional methods. The high density article is then heat treated in a manner to suit specific product requirements. The mechanical properties achieved by the claimed process offer significant benefits when compared to conventionally processed sintered powder metal articles.
