Forged Metal Powder Products.
Abstract
Minimum deformation forging of prealloyed steel powders was used to produce complex-shaped components having a quality level equivalent to conventional forgings. Various 4600 and 4300 prealloyed steel powders, mixed with graphite to give 0.40% carbon, were investigated. Sintered compacts were forged with conventional and minimum-deformation type tooling. Minimum deformation forging produced high-quality flash-free forgings with no draft angles. Results of the study on the 4640 composition have shown that P/M forgings are competitive with conventionally wrought materials. Forgings with near theoretical density (99% plus) were capable of providing notched impact strength and ductility comparable to bar stock forgings. (Author)
