Definitions

  • This invention relates to a net or near net shape powder metallurgy process.
  • the invention relates particularly, but not exclusively, to the provision of an atomic diffusion filter between a graphite former, used to derive the finished net or near net shape form used in the manufacture of near net shape powder metallurgy components.
  • a known manufacturing method used for producing components and materials utilises the consolidation of metal powders by Hot Isostatic Pressing.
  • a pre-consolidation of the metal powders may or may not be used utilising Cold Isostatic Pressing.
  • metal powder is placed in a containment and a vacuum is applied within the containment, and the containment is sealed. This then may or may not be partially consolidated in a cold form by subjecting the containment to a cold Isostatic process (CIPing). The contained powder is then subjected to Hot Isostatic Pressing (HIPing).
  • CIPing cold Isostatic process
  • HIPing Hot Isostatic Pressing
  • the HIPing process utilises the application of heat at approximately, but not essentially, 80% of solidus of the material of which the powder is derived.
  • This process subjects the metal powder to thermo mechanical stress whereby the metal powders are mechanically deformed in a super plastic condition.
  • the resulting intimate contact and movement between the powder particles results in a shear and compressive stresses being placed upon them.
  • an atomic interaction (interdiffusion) between the particles takes place subsequently removing all prior practical history thus creating a solid homogenous metal form.
  • US2004/055416 describes hot isostatic pressing of a homogenously mixed composition of copper and carbon.
  • GB941795 describes a sintered metal powder compressed by way of a rolling process.
  • the nickel based alloy has the following composition by weight percent: C 1.0, Cr 15, Si 4.0, B 3.5, Fe 4.5, Ni balance.
  • the component is greater than 2 metres in length.
  • the component is a motor or pump.
  • a Nickel based alloy is typically:-
  • a Ferrous alloy is typically;
  • the diffusion of carbon into other alloy steels followed by an appropriate heat treatment may be beneficial to increase both stiffness and the surface performance of components even though the materials are not ordinarily treated in such a way.
  • the duration of the peak HIPing temperature can be adjusted to optimise the depth of carbon diffusion; provided the increase in time does not have a detrimental effect upon the overall morphology of the consolidated material. For example increased grain growth and/or undesirably affect the volume fraction or dimensions of precipitates.
