Thus, metallic glasses are suitable for an exceptional number of high-tech applications. They are energy-absorbing and scratch-proof while still having very good spring characteristics – interesting for applications such as injection nozzle, diaphragms, casing for consumer electronics, or as dome tweeters for speakers to mention only a few.
About Heraeus AMLOY - Amorphous Metals
Amorphous metals are frozen in their liquid condition during the casting process. The absence of lattice defects drive the excellent mechanical properties, the outstanding corrosion resistance, biocompatibility and isotropic behavior.
What is an amorphous metal?
During the casting of metals and metallic alloys nuclei of crystals are formed and tend to grow in a second stage of solidification. Grain size, shape, orientation as well as distribution of the alloying elements depend strongly on the cooling conditions. The imperfection of the lattice structure is driving the mechanical and electromagnetic properties of the material in one or the other direction. Impurities along grain and/or phase boundaries drive predisposition against corrosion, brittleness or poor fracture toughness.
Due to the absence of lattice defects, i.e. no grain and phase boundaries and no related composition variations, amorphous metals are also known as liquid metal, metallic glass or BMG (Bulk Metallic Glasses).
