  2. Superhard material - Wikipedia

    en.wikipedia.org/wiki/Superhard_material

    As diamond is less stable than graphite, c-BN is less stable than h-BN, but the conversion rate between those forms is negligible at room temperature. [ 30 ] Cubic boron nitride is insoluble in iron, nickel, and related alloys at high temperatures, but it binds well with metals due to formation of interlayers of metal borides and nitrides.

  3. Water-reactive substances - Wikipedia

    en.wikipedia.org/wiki/Water-reactive_substances

    The alkaline earth metals (Be, Mg, Ca, Sr, Ba, and Ra) are the second most reactive metals in the periodic table, and, like the Group 1 metals, have increasing reactivity with increasing numbers of energy levels. Beryllium (Be) is the only alkaline earth metal that does not react with water or steam, even if the metal is heated red hot. [9]

    In the lore of both versions of the game, the special treatment this metal gets is evident in the requirement to complete a quest assigned by the Guildmaster of the Champion's Guild in order to wear a platebody of this metal. [75] [76] This metal is stronger than other well-known fictional metals that also exist in the game, such as Mithril and ...

  5. Strengthening mechanisms of materials - Wikipedia

    en.wikipedia.org/wiki/Strengthening_mechanisms...

    Brass, a binary alloy of copper and zinc, has superior mechanical properties compared to its constituent metals due to solution strengthening. Work hardening (such as beating a red-hot piece of metal on anvil) has also been used for centuries by blacksmiths to introduce dislocations into materials, increasing their yield strengths.

  6. Prince Rupert's drop - Wikipedia

    en.wikipedia.org/wiki/Prince_Rupert's_drop

    Prince Rupert's drops are produced by dropping molten glass drops into cold water. The glass rapidly cools and solidifies in the water from the outside inward. This thermal quenching may be described by means of a simplified model of a rapidly cooled sphere. [ 3 ]

  7. Corrosion engineering - Wikipedia

    en.wikipedia.org/wiki/Corrosion_engineering

    Recycled water typically has a higher salt content than potable drinking water, meaning that it is more corrosive than regular tap water. The same risk from damage and water spray exists for above ground piping and backflow preventers. Fiberglass covers, cages, and concrete footings have worked well to keep tools at an arm's length.

  8. Tempering (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/Tempering_(metallurgy)

    Tempering was usually performed by slowly, evenly overheating the metal, as judged by the color, and then immediately cooling, either in open air or by immersing it in water. This produced much the same effect as heating at the proper temperature for the right amount of time, and avoided embrittlement by tempering within a short time period.

  9. Maraging steel - Wikipedia

    en.wikipedia.org/wiki/Maraging_steel

    Maraging blades are superior for foil and épée because crack propagation in maraging steel is 10 times slower than in carbon steel, resulting in less frequent breaking of the blade and fewer injuries. [i] [20] Stainless maraging steel is used in bicycle frames (e.g. Reynolds 953 introduced in 2013) [21] and golf club heads. [22]
