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 PM 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
