  2. Superhard material - Wikipedia

    en.wikipedia.org/wiki/Superhard_material

    A superhard material is not necessarily "supertough". For example, the fracture toughness of diamond is about 7–10 MPa·m 1/2, [16] [17] which is high compared to other gemstones and ceramic materials, but poor compared to many metals and alloys – common steels and aluminium alloys have the toughness values at least 5 times higher. [18]

    Blueish metal, named after the game it features in; also commonly called 'rune'. In earlier versions of the game and the Old School game, it is the toughest workable metal, [73] and in the main game it is both the strongest workable metal in the free-to-play version, as well as being the main ingredient in the Elder Rune metal.

    One of the primordial nuclides is tantalum-180m, which is predicted to have a half-life in excess of 10 15 years, but has never been observed to decay. The even-longer half-life of 2.2 × 10 24 years of tellurium-128 was measured by a unique method of detecting its radiogenic daughter xenon-128 and is the longest known experimentally measured ...

    AUS-10 (10A) is comparable to 440C with a carbon content close to 1.10%. [7] It is slightly tougher than 440C. CPM SxxV series. The SxxV series are Crucible Industries [13] stainless steels produced using CPM process. [14] CPM S30V, [35] on the lower end of the SxxV steels, it has a carbon content of 1.45%. However, S30V is still considered to ...

    Transparent real-life aluminum compounds or aluminum metal. An aluminum windowpane, "of glass-like transparency" was reported from Germany in 1933. [1] Corundum (Al 2 O 3) is transparent and is widely used in commercial and industrial settings. It has a hardness of 9 Mohs, making it the third hardest mineral after diamond and moissanite.
