Preface
Aluminium alloy has taken over as the most popular material for structural com-
ponents in engineering industry included automotive, aerospace and construction
industries for several reasons. The most characteristic properties of aluminium are
low specifi c weight and low melting point. In addition, aluminium has excellent
corrosion resistance, high strength and stiff ness to weight ratio, good formability,
weldability, high electrical and heat conductivity. Last but not least, aluminium al-
loy components are particularly required for environmental, ecological and eco-
nomical aspects.
The book provides a theoretical and a practical understanding of the metallurgical
principles in: severe plastic deformation processes with respect to high strength and
ductility achieved on bulk and PM aluminium and aluminium alloys; welding of
aluminium, mainly focused on a relatively new technique of friction stir welding
as well as welded fatigue behaviour; cyclic deformation behaviour of the alumini-
um alloys at room and elevated temperature forcefully on the load sequence eff ects
in fatigue crack propagation and crack growth under loading; creep-fatigue crack
growth; modelling of precipitation hardening in casting aluminium alloys; an aniso-
tropic behaviour analysis undergoing large plastic deformations; new approaches to
reaction kinetics during molten aluminium refi ning using electron backscatt er dif-
fraction; theoretical explanation about number restoration and etching techniques
applied to recover the obliterated markings on aluminium and aluminium alloys
and information about machining and machinability of aluminium alloys.
Out of all, aluminium alloys off er opportunities in a wide range of applications.
The present book enhances in detail the scope and objective of various develop-
mental activities of the aluminium alloys. A lot of research on aluminium alloys
has been performed. Currently, the research eff orts are connected to the relatively
new methodics and processes. We hope that people new to the aluminium alloys
investigation will fi nd this book to be of assistance for the industry and university
fi elds enabling them to keep up-to-date with the latest developments in aluminium
alloys research.
