  2. Vacuum furnace - Wikipedia

    en.wikipedia.org/wiki/Vacuum_furnace

    Vacuum furnaces capable of temperatures above 1200 °C are used in various industry sectors such as electronics, medical, crystal growth, energy and artificial gems. The processing of high temperature materials, both of metals and nonmetals, in a vacuum environment allows annealing , brazing , purification , sintering and other processes to ...

  3. Sintering - Wikipedia

    en.wikipedia.org/wiki/Sintering

    Sintering or frittage is the process of compacting and forming a solid mass of material by pressure [1] or heat [2] without melting it to the point of liquefaction. Sintering happens as part of a manufacturing process used with metals, ceramics, plastics, and other materials. The atoms/molecules in the sintered material diffuse across the ...

  5. Sinter plant - Wikipedia

    en.wikipedia.org/wiki/Sinter_plant

    The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical properties of the ingredients. The purpose of sinter are to be used converting iron into steel. Sinter plants, in combination with blast furnaces, are also used in non-ferrous smelting.

  6. Vacuum arc remelting - Wikipedia

    en.wikipedia.org/wiki/Vacuum_arc_remelting

    Vacuum arc remelting (VAR) is a secondary melting process for production of metal ingots with elevated chemical and mechanical homogeneity for highly demanding applications. [1] The VAR process has revolutionized the specialty traditional metallurgical techniques industry, and has made possible tightly controlled materials used in biomedical ...

  7. Powder metallurgy - Wikipedia

    en.wikipedia.org/wiki/Powder_metallurgy

    Programmable sintering furnace with a controllable temperature program, used to sinter ceramics. Most sintering furnaces contain three zones with three different properties that help to carry out the six steps above. The first zone, commonly coined the burn-off or purge stage, is designed to combust air, burn any contaminants such as lubricant ...

  8. Electron-beam additive manufacturing - Wikipedia

    en.wikipedia.org/wiki/Electron-beam_additive...

    Metal powders can be consolidated into a solid mass using an electron beam as the heat source. Parts are manufactured by melting metal powder, layer by layer, with an electron beam in a high vacuum. This powder bed method produces fully dense metal parts directly from metal powder with characteristics of the target material. The EBM machine ...

  9. Electron-beam furnace - Wikipedia

    en.wikipedia.org/wiki/Electron-beam_furnace

    Electron-beam furnaces are used for production and refining of high-purity metals (especially titanium, vanadium, tantalum, niobium, hafnium, etc.) and some exotic alloys. [1] The EB furnaces use a hot cathode for production of electrons and high voltage for accelerating them towards the target to be melted.
