There is provided a method for the manufacture of a metal part from powder comprising the steps: a) providing a spherical metal powder, b) mixing the powder with a hydrocolloid in water to obtain an agglomerated metal powder, c) compacting the agglomerated metal powder to obtain a part of compacted agglomerated metal powder,wherein the structure of the part is open,d) debinding the part to remove the hydrocolloid, e) compacting the part using high velocity compaction (HVC) preferably to a density of more than 95% of the full theoretical density,f) further compacting the part using hot isostatic pressing (HIP) preferably to more than 99 % of the full theoretical density to obtain a finished metal part, wherein at least one oxide is added to the metal powder before step c), which oxide has a melting point higher than the melting point of the metal powder. |
