What is the amorphous metal?

amorphous metal is a metal with a disturbed atomic structure, unlike most metals that have a regular structure. These substances are also called metal glasses, because one way of producing amorphous metals is similar to the procedure for glass production, but instead of silica oxide using metal. Studies show that amorphous metals can be more than twice as strong as normal metal and are ideal for military armor, weighing the same as normal metal. Due to the disturbed material structure, it is also more resistant to corrosion and wear.

The amorphous metals were first created in Caltech Pol Duwez in 1957. Duwez created an amorphous metal by cooling alloy (au _{80 Si 20 ) from a liquid state below a fraction of a second. The cooling rate had to exceed a million degrees of Kelvin per second, so in milliseconds there had to be cooling the metal from liquid state to a solid state. Cooling it quickly prevented metal crystallization similar to a typical metal that gives it its unique amorphous structureuru. In the beginning, the forms of amorphous metal were limited, consisting mainly of thin ribbons, foils and wires. These limitations were forced by the need for rapid cooling speed.}

The

amorphous metal suitable for commercialization was first produced in 1976 C. Graham and H. Liebermann. They used a super -cooled fast -growing wheel to create the volume of amorphic metal suitable for transformers of low -loss energy distribution, commercialized under the name Metglas. Amorphic metal can be rapidly magnetized and demagnetized, leading to energy savings when used in transformers on an electric grid. 70-80% less energy is consumed by amorphous metal transformers, reducing emissions by _{2 and energy savings. Today, amorphous metal transformers are used widely in India and China, where they were used to successfully cut greenhouse gas emissions.}

during the 80s.They experimented with different alloys to reduce the necessary cooling speed for creating amorphous metals. They managed to reduce the degree of critical cooling from hundreds of Kelvins per second to only one kelvin per second, so the production of mass metal glasses is more feasible. In 2004, scientists succeeded in mass amorphous steel and prepared a way for wider commercialization of material.
