Tempering provides a way to carefully decrease the hardness of the steel, thereby increasing the toughness to a more desirable point. Cast steel is often normalized rather than annealed, to decrease the amount of distortion that can occur. Tempering can further decrease the hardness, increasing the ductility to a point more like annealed steel. [8]
41xx steel is a family of SAE steel grades, as specified by the Society of Automotive Engineers (SAE). Alloying elements include chromium and molybdenum, and as a result these materials are often informally referred to as chromoly steel (common variant stylings include chrome-moly, cro-moly, CrMo, CRMO, CR-MOLY, and similar).
Normalizing not only produces pearlite but also martensite and sometimes bainite, which gives harder and stronger steel but with less ductility for the same composition than full annealing. In the normalizing process the steel is heated to about 40 degrees Celsius above its upper critical temperature limit, held at this temperature for some ...
Natural blue or blue-gray diamonds, common for the Argyle diamond mine in Australia, are rich in hydrogen; these diamonds are not semiconductors and it is unclear whether hydrogen is actually responsible for their blue-gray color. [21] Natural blue diamonds containing boron and synthetic diamonds doped with boron are p-type semiconductors.
Detailed view of the recreated great Golden Fleece of king Louis XV of France. Below the 107 carats (21.4 g) spinel Côte de Bretagne hangs the French Blue diamond and the fleece itself, set with hundreds of yellow diamond replicas. The Tavernier Blue was the precursor diamond to the Blue Diamond of the French Crown (aka the French Blue).

Morton vs. Diamond Crystal. Morton has been headquartered in Chicago since 1848, and in 1914 introduced the iconic umbrellaed Morton Salt Girl to emphasize the free-flowing quality of its table ...
The color produced is a blue to blue-green which penetrates the whole stone. Such diamonds are not annealed. The blue color can sometimes approach that of natural Type IIb diamonds, but the two are distinguished by the latter's semiconductive properties. As with most irradiated diamonds, most gamma ray-treated diamonds were originally tinted ...
