2 Introduction The emphasis thus far has been on crystalline materials. There are numerous engineering materials that lack the long range translational periodicity of a crystalline material. These non-crystalline materials are referred to as either- amorphous, glassy, or super-cooled liquids . Theoretically, any material can form an amorphous structure if the cooling rate from the melt is sufficiently rapid to suppress crystal formation . This chapter will emphasize the structural considerations that facilitate the development of an amorphous structure.
