Vitreous glass

-

Glassy steel - the name proposed for a particular type of steel, characterized by an amorphous structure more similar to glass than to classic steel.

This variant was developed by researchers from the American Oak Ridge National Laboratory (also at the University of Virginia) in 2004. The chemical composition of the alloy is, in addition to the iron and carbon found in each steel, also boron, chromium, cobalt, molybdenum, manganese and about 1.5% yttrium. The latter is critical: it slows down the growth of crystals usually occurring during steel cooling; Other lanthanides can also be used in place of yttrium.

Steel is much more traditional than steel, but it is also brighter. It also has a higher corrosion resistance than conventional steel, and does not exhibit ferromagnetic properties at room temperature. Research continues on the development of a less corrosive glass technology and in larger quantities (for now, bars are no larger than 12 millimeters wide.) Bibliography
