Preface
Aluminum alloys are not only serving aerospace, automotive and renewable energy indus‐
try they are being extensively used in surface modification processes at nanoscale such as
modified phosphoric acid anodizing process to create high surface activity of nanoparticles.
Benign joining of ultra-fine grained aerospace aluminum alloys using nanotechnology is
highly promising. Super hydrophobic surfaces have been created at a nanoscale to make the
surfaces dust and water repellent. The biggest challenge lies in producing nanostructure
metals at competitive costs. Severe plastic deformation (SPD) is being developed to produce
nonmaterial for space applications. The focus of scientists on using aluminum alloys for di‐
rect generation of hydrogen is rapidly increasing and dramatic progress has been made in
fabrication of Aluminum, Gallium and Indium alloys. It can therefore seen that the impor‐
tance of aluminum has never declined and it continues to be material which has attracted
the attention of scientists and engineers in all emerging technologies.
In the context of the above comments, there is ample justification for publishing this book.
The chapter by Prof. Sahin Mumin describes some of the important fundamental properties
related to metallurgical properties and welding. The procedure and structural details of fric‐
tion stir welding and friction stir channeling has been demonstrated by Dr. Vilaça Pedro
with beautiful illustrations, deep rolling ageing and and fatigue control the surface proper‐
ties of auminium alloys. Dr.Ing. Juijerm Pathipham, has described the impact of the above
factors comprehensively. Prof. Sklenicka Vadov has described the equal channel angular
pressing in relation to producing ultra five grains materials with profuse illustrations and
graphics. The readers interested in numerical modeling would find the chapter on numeri‐
cal modeling very productive. Chapter on machanability by Prof. Songmene Victor focuses
on auminum, magnesiun and silicon alloys. The effect of micro arc oxidation coating on
structure and mechanical parameters has been shown by Prof. Sahin Mumin. Aluminum is
being increasingly used in solar power due to its attributes and it is extensively used in con‐
centrating solar power (CSP) and photovoltalic solar cells (PV). The reader interested in re‐
newable energy would find the chapter on aluminum alloys in solar power highly interest‐
ing. The section of corrosion of PV modules has been written comprehensively in this chap‐
ter. It is a good example of international collaboration as shown by the authors from Iran,
Canada, Pakistan and Saudi Arabia. InTech is to be congratulated for bringing a book on
Aluminum alloys with new dimensions proliferating in venues of emerging technologies. I
hope students at graduate level and all the researchers would find this book of great interest
and severe topic would stimulate them in undertaking further research in areas of interest.
