摘要： A method for the manufacture of a metal part, the method including the steps: a) compacting agglomerated spherical metal powder to a preform, b) debinding and sintering the preform to a part at a temperature not exceeding 1275° C., c) performing one of the following steps: i) compacting the part to a density of more than 95% of the theoretical density, or ii) compacting the part to a density of less than 95% of the theoretical density and sintering the part at a temperature not exceeding 1275° C. to a density of more than 95% of the theoretical density, and d) subjecting the part to hot isostatic pressing at a temperature not exceeding 1200° C. The method provides an industrial process to produce fully dense parts from alloys which normally cannot be produced and still give good impact properties, which is vital for many applications where there alloys are used.

摘要： A method for the manufacture of a multilevel metal part, the method including the steps of: a) compacting agglomerated spherical metal powder to a green multilevel preform such that an open porosity exists, wherein the green multilevel preform fulfills the relation zg=zHVC·a, b) debinding the green preform, c) sintering the green preform in an atmosphere including hydrogen, d) compacting the green preform with high velocity compaction to a density of at least 95% TD, e) subjecting the part to densification to a density of at least 99% TD. There is further provided a multilevel metal part. Advantages of the method include that it is possible to manufacture a multilevel part which is essentially uniform throughout the entire part and which has excellent tolerance, which at the same time has virtually full density and thereby having excellent mechanical properties as well as excellent corrosion properties.
