Metallic glasses along with amorphous structures were discovered in 1960 with great scientific, and technological interest. The search for new and advanced materials has been the major preoccupation of materials scientists during the past several years. Significant improvements have been achieved in the mechanical, chemical and physical properties of materials. Metallic materials are traditionally considered crystalline in nature, possessing translational symmetry, that is, their constituent atoms are arranged in a regular and periodic manner in all three dimensions. However, a revolution in the concept of metals was brought about in 1960 when Pol Duwez, at the California Institute of Technology in Pasadena, California, had synthesized an Au-Si alloy in glassy state by rapidly solidifying the liquid at rates approaching a million degrees per second. Glass is any noncrystalline solid obtained by continuous cooling from the liquid state, and amorphous solid is any noncrystalline material obtained by any other method, except by continuous cooling from liquid state. In the first chapter of this work we saw historical development of bulk metallic glasses including the technics of their production. In the second chapter we talked about metallic glasses generally, about glass forming ability and about thermodynamics and kinetics of glass formation. Third chapter was dedicated to methods of obtaining metallic glasses. There we talked about advantages and disadvantages of each method. In the next chapter we saw some important physical properties of bulk metallic glasses: density, electrical resistance, viscosity, thermal conductivity. The last chapter is dedicated to a large number of applications of bulk metallic glasses.
