  2. Hardened steel - Wikipedia

    en.wikipedia.org/wiki/Hardened_steel

    A talented smith or metalworker can fine-tune the performance of a steel tool or item to precisely what is required based solely on careful observation of temper colours. A visual representation of this process may make the concept easier to understand. A masonry drill bit made of hardened steel. Hardened steel 3D printing nozzle

  3. Conan Exiles - Wikipedia

    en.wikipedia.org/wiki/Conan_Exiles

    Conan Exiles is a survival video game developed and published by Funcom for PlayStation 4, Windows, and Xbox One. The game is set in the world of Conan the Barbarian, with the custom playable character being rescued by Conan, beginning their journey. Early access versions of the game were released in early 2017, leaving early access on 8 May ...

  4. Ferrocerium - Wikipedia

    en.wikipedia.org/wiki/Ferrocerium

    Ferrocerium is used in fire lighting in conjunction with a striker, similarly to natural flint-and-steel, though ferrocerium takes on the opposite role to the traditional system; instead of a natural flint rock striking tiny iron particles from a firesteel, a striker (which may be in the form of hardened steel wheel) strikes particles of ...

  5. Case-hardening - Wikipedia

    en.wikipedia.org/wiki/Case-hardening

    This causes carbon to diffuse into the surface of the steel. The depth of this high carbon layer depends on the exposure time, but 0.5mm is a typical case depth. Once this has been done the steel must be heated and quenched to harden this higher carbon 'skin'. Below this skin, the steel core will remain soft due to its low carbon content.

  6. Boron steel - Wikipedia

    en.wikipedia.org/wiki/Boron_steel

    The introduction of boron steel elements introduced issues for accident scene rescuers as its high strength and hardness resisted many conventional cutting tools (hydraulic rescue tools) in use at that time. [3] [4] Flat boron steel for automotive use is hot stamped in cooled molds from the austentic state (obtained by heating to 900-950 °C ...

  7. 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.

  8. Bunnock - Wikipedia

    en.wikipedia.org/wiki/Bunnock

    Bunnock (also known as the game of bones or simply bones) is a throwing game that is thought to have Russian origin. [1] The aim of Bunnock is to throw bones at an oppositions rows of bones, trying to do so in the fewest throws possible. The team that knocks down all of the oppositions bones first, wins.

  9. Work hardening - Wikipedia

    en.wikipedia.org/wiki/Work_hardening

    The work-hardened steel bar has a large enough number of dislocations that the strain field interaction prevents all plastic deformation. Subsequent deformation requires a stress that varies linearly with the strain observed, the slope of the graph of stress vs. strain is the modulus of elasticity, as usual.
