ABSTRACT
A variety of alloys with different constitutions have been synthesized by mechanical alloying. These alloy phases include solid solutions (both equilibrium and metastable), intermediate phases (quasi-crystalline and equilibrium or metastable crystalline phases), and amorphous alloys. The types of materials investigated include metallic, ceramic, polymeric, and composites. Even though the number of phases reported to form in different alloy systems is unusually large [1], and property evaluations have been done in only some cases, and applications have been explored (see Chapters 9, 10, 12, and 17 for details), the number of investigations devoted to an understanding of the mechanism through which the alloy phases form is very limited. This chapter summarizes the information available in this area.
