  2. Cryogenic treatment - Wikipedia

    en.wikipedia.org/wiki/Cryogenic_treatment

    A cryogenic treatment is the process of treating workpieces to cryogenic temperatures (typically around -300°F / -184°C, or as low as −190 °C (−310 °F)) in order to remove residual stresses and improve wear resistance in steels and other metal alloys, such as aluminum.

  3. Cryogenic hardening - Wikipedia

    en.wikipedia.org/wiki/Cryogenic_hardening

    Cryogenic hardening is a cryogenic treatment process where the material is cooled to approximately −185 °C (−301 °F), typically using liquid nitrogen. It can have a profound effect on the mechanical properties of certain steels , provided their composition and prior heat treatment are such that they retain some austenite at room temperature.

  4. Cryogenics - Wikipedia

    en.wikipedia.org/wiki/Cryogenics

    Nitrogen is a liquid under −195.8 °C (77.3 K).. In physics, cryogenics is the production and behaviour of materials at very low temperatures.. The 13th International Institute of Refrigeration's (IIR) International Congress of Refrigeration (held in Washington DC in 1971) endorsed a universal definition of "cryogenics" and "cryogenic" by accepting a threshold of 120 K (−153 °C) to ...

  5. Cryocooler - Wikipedia

    en.wikipedia.org/wiki/Cryocooler

    An important component of refrigerators, operating with oscillatory flows, is the regenerator. A regenerator consists of a matrix of a solid porous material, such as granular particles or metal sieves, through which gas flows back and forth. Periodically heat is stored and released by the material.

  6. Cryogenic engineering - Wikipedia

    en.wikipedia.org/wiki/Cryogenic_engineering

    Cryogenic engineering is a sub stream of mechanical engineering dealing with cryogenics, and related very low temperature processes such as air liquefaction, cryogenic engines (for rocket propulsion), cryosurgery. Generally, temperatures below cold come under the purview of cryogenic engineering.

  7. Cryogenic processor - Wikipedia

    en.wikipedia.org/wiki/Cryogenic_processor

    A cryogenic processor is a device engineered to reduce the temperature of an object to cryogenic levels, typically around −300°F (−184.44°C), at a moderate rate in order to prevent thermal shock to the components being treated. The inception of commercial cryogenic processors dates back to the late 1960s, pioneered by Ed Busch. [1]

  9. Cryostat - Wikipedia

    en.wikipedia.org/wiki/Cryostat

    A cryostat (from cryo meaning cold and stat meaning stable) is a device used to maintain low cryogenic temperatures of samples or devices mounted within the cryostat. Low temperatures may be maintained within a cryostat by using various refrigeration methods, most commonly using cryogenic fluid bath such as liquid helium. [1]
