  2. Powder metallurgy - Wikipedia

    en.wikipedia.org/wiki/Powder_metallurgy

    Iron powder is commonly used for sintering. Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal powders.PM processes are sometimes used to reduce or eliminate the need for subtractive processes in manufacturing, lowering material losses and reducing the cost of the final product. [1]

  3. Metal powder - Wikipedia

    en.wikipedia.org/wiki/Metal_powder

    The following processes can be used to produce metal powder: [6] Direct reduction is the result of blending carbon with iron oxide ore, heating the mixture, removing the sponge iron from the carbon, grinding it, annealing it, and regrinding to make the powder form usable for manufacturing.

  4. Mechanical powder press - Wikipedia

    en.wikipedia.org/wiki/Mechanical_powder_press

    The function principles of the mechanic press machines differ in how to ensure the upper punch–main movement by cams, spindles-and friction drives, eccentric, knuckle-joints or by the round table principle, independent if the die-or lower punch movement is realized by cams- or eccentric systems or other mechanically or hydraulically combined ...

  5. Titanium powder - Wikipedia

    en.wikipedia.org/wiki/Titanium_powder

    In the direct powder rolling (DPR) process BE powder is used to produce sheet and plate and composite multilayered sheet and plates. Sheets between 1.27 and 2.54 mm and 50 to 99+% dense of single layer CP titanium, Ti Grade 5, TiAl (Ti-48Al-2Cr-2Nb) and composite Ti/Grade 5/Ti and Grade 5/TiAl/Grade 5 have been produced by DPR and sintering.

  6. 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.

  7. Refractory metals - Wikipedia

    en.wikipedia.org/wiki/Refractory_metals

    The ignition is easier and the arc burns more stably than without the addition of thorium. For powder metallurgy applications, binders have to be used for the sintering process. For the production of the tungsten heavy alloy, binder mixtures of nickel and iron or nickel and copper are widely used. The tungsten content of the alloy is normally ...

  8. Pelletizing - Wikipedia

    en.wikipedia.org/wiki/Pelletizing

    Pelletizing is the process of compressing or molding a material into the shape of a pellet. A wide range of different materials are pelletized including chemicals, iron ore, animal compound feed, plastics, waste materials, and more.

  9. Extractive metallurgy - Wikipedia

    en.wikipedia.org/wiki/Extractive_metallurgy

    Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied. The field is a materials science, covering all aspects of the types of ore, washing, concentration, separation, chemical processes and extraction of pure metal and their alloying to suit various applications, sometimes for direct ...
