  2. Hot isostatic pressing - Wikipedia

    en.wikipedia.org/wiki/Hot_isostatic_pressing

    The HIP process subjects a component to both elevated temperature and isostatic gas pressure within a high-pressure containment vessel, unlike the cold isostatic pressing (CIP), where the component is maintained at room temperature. [1] The pressurizing gas most widely used is argon. An inert gas is used so that the material does not chemically ...

  3. Sintering - Wikipedia

    en.wikipedia.org/wiki/Sintering

    A commonly used second external force is pressure. Sintering performed by only heating is generally termed "pressureless sintering", which is possible with graded metal-ceramic composites, utilising a nanoparticle sintering aid and bulk molding technology. A variant used for 3D shapes is called hot isostatic pressing.

  4. Cemented carbide - Wikipedia

    en.wikipedia.org/wiki/Cemented_carbide

    Cemented carbides are a class of hard materials used extensively for cutting tools, as well as in other industrial applications. It consists of fine particles of carbide cemented into a composite by a binder metal. Cemented carbides commonly use tungsten carbide (WC), titanium carbide (TiC), or tantalum carbide (TaC) as the aggregate. Mentions ...

  5. Hot pressing - Wikipedia

    en.wikipedia.org/wiki/Hot_pressing

    Hot pressing is a high-pressure, low-strain-rate powder metallurgy process for forming of a powder or powder compact at a temperature high enough to induce sintering and creep processes. [1] This is achieved by the simultaneous application of heat and pressure. Hot pressing is mainly used to fabricate hard and brittle materials.

  6. Titanium powder - Wikipedia

    en.wikipedia.org/wiki/Titanium_powder

    Hot isostatic pressing (HIP) can further increase the density of these parts and produce components more economically than cast or wrought parts, but the porosity present in the material degrades fatigue and fracture properties. The BE approach has been used to produce valves for the Toyota Altezza, golf club heads and softball bats. [4]

  7. Types of press tools - Wikipedia

    en.wikipedia.org/wiki/Types_of_press_tools

    Press tools are commonly used in hydraulic, pneumatic, and mechanical presses to produce the sheet metal components in large volumes. Generally press tools are categorized by the types of operation performed using the tool, such as blanking, piercing , bending , forming , forging , trimming etc.

  8. Severe plastic deformation - Wikipedia

    en.wikipedia.org/wiki/Severe_Plastic_Deformation

    Processes such as ECAE and HPT have also been used to consolidate metal powders and composites without the need for the high temperatures used in conventional consolidation processes such as hot isostatic pressing, allowing desirable characteristics such as nanocrystalline grain sizes or amorphous structures to be retained. [24] [25]

  9. Ceramic forming techniques - Wikipedia

    en.wikipedia.org/wiki/Ceramic_forming_techniques

    Isostatic presses can be either high speed, high output type of automatic presses for such parts as ceramic insulators for spark plugs or sand blast nozzles, or slower operating "wet bag" presses that are much more manual in operation but suitable particularly for large machinable blanks or blanks that will be cut or otherwise formed in ...
