  • Dense parts produced by uniaxial compressing an agglomerated spherical metal powder
    Patent number: 6334882
    Abstract: The invention refers to a process for compressing a spherical metal powder, agglomerated with at least 0.5% by weight of a thermo-reversible hydrocolloid as a binder, in a uniaxial press operation with a ram speed of over 2 m/s to a green body having a high density. More particularly the invention also refers to a process for sintering said green bodies to products with full or near full density. The products obtained can be high resistant, high strength details or parts of stainless steel or other alloys.
