Consolidation of Mechanically Alloyed Powders

The consolidation of mechanically alloyed powders is a critical process in the field of materials science and metallurgy. Mechanically alloyed powders are synthesized through high-energy ball milling, resulting in finely divided and intimately mixed powder particles. This chapter provides an overview of the consolidation techniques employed to transform these mechanically alloyed powders into functional and advanced materials. Various consolidation methods, such as hot isostatic pressing, spark plasma sintering, powder extrusion, powder forging, solid and liquid state sintering, reaction sintering, selective laser sintering, and microwave sintering are discussed. Also, the chapter explores the effects of consolidation parameters, such as temperature, pressure, and holding time, on the properties of the final product. Further, it includes various advantages, challenges and applications of several consolidation techniques.
