  • High density forming process with powder blends
    Patent number: 6143240
    Abstract: 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.
