Fabrication Methods for Bulk Amorphous Alloys
Amorphous alloys are one of the newer groups of functional materials that are widely used in many industries. Their properties are much better than materials with the same chemical composition and crystal structure. Amorphous alloys are produced by rapid cooling techniques. The most popular methods are: melt‐spinning method, injection method, suction method, centrifugal method. Using these methods, products of various shapes can be produced. There are two groups of amorphous materials: conventional in the form of a thin tape and bulk amorphous materials with a thickness of more than 100 μm and various shapes, e.g. rods, tubes, plates, etc. The era of bulk amorphous material began when A. Inoue of Tohoku University in Japan developed three criteria. These criteria make it possible to systematically manufacture massive amorphous materials. Of course, there are many restrictions on their production, but the date 1989 is the date of birth of a new group of materials, i.e. bulk amorphous alloys. Material engineers need such materials and their development is continuous, as evidenced by numerous scientific publications in this field. It should be assumed that the growing demands on modern materials will promote the development of this group of materials.
