Book Description
Most of the powder metallurgical research on particulate aluminum alloys has been focused on optimizing composition. However, the role of process parameters on sinterability of prealloyed powders still remains to be critically evaluated. First part of the study logically evaluates the effect of sintering atmosphere (nitrogen, argon and vacuum) and temperature on sintered density, electrical, electrochemical and mechanical properties of Al-Cu-Mg, Al-Mg-Si and Al-Zn-Mg alloys. The effect of heat treatment (T4, T6 and T8 tempers) on microstructure and properties was also investigated. In an attempt to make the process less energy intensive and control the grain growth at higher temperature, in second part of the study, higher heating rates were implemented using multimode microwave (2.45 GHz and 6kW) furnace. Microstructural changes and properties were compared between microwave and conventional heated compacts. This book should help to shed some knowledge on new processing technologies, interaction of microwave with conductive materials and especially useful to researchers, professionals and students working in the field of aluminum powder metallurgy and microwave processing.

Book Description
The major issue of energy saving and conservation of the environment in the world is being emphasized to us to concentrate on lightweight materials in which aluminium alloys are contributing more in applications in the twenty-first century. Aluminium and its related materials possess lighter weight, considerable strength, more corrosion resistance and ductility. Especially from the past one decade, the use of aluminium alloys is increasing in construction field, transportation industries, packaging purposes, automotive, defence, aircraft and electrical sectors. Around 85% is being used in the form of wrought products, which replace the use of cast iron. Further, the major features of aluminium alloy are recyclability and its abundant availability in the world. In general, aluminium and its related materials are being processed via casting, drawing, forging, rolling, extrusion, welding, powder metallurgy process, etc. To improve the physical and mechanical properties, scientists are doing more research and adding some second-phase particles in to it called composites in addition to heat treatment. Therefore, to explore more in this field, the present book has been aimed and focused to bridge all scientists who are working in this field. The main objective of the present book is to focus on aluminium, its alloys and its composites, which include, but are not limited to, the various processing routes and characterization techniques in both macro- and nano-levels.

Book Description
This research work involves macro and micro scale processing of Al-alloys. At micro level, pillars were generated from AL-Sn-Mg powders and binder mixture. Both conventional and current activated sintering processes were investigated in order to do sintering. Two types of binders and solvent system were investigated. Paraffin wax (PW) and n-heptane was used with AL-Sn-Mg powders and polyethylene glycol (PEG) and water was used with Al-SN powders. Setup was designed and fabricated to generate pillars and for DC current activated sintering. Rolling technique and very low pressure was applied in this application. At macro level, press and sinter technique was investigated to compare the mechanical properties such as density, hardness and shrinkage of mechanically alloyed Al-Sn-Mg powders and unmilled powders. The result shows that the MA powders have higher mechanical properties compared to unmilled powders. However, unmilled powder compact sintered very nicely and used for further processing. Green pillars were successfully generated using both binder systems. For sintering, conventional sintering appeared more successful than current activated sintering.
