The sixth in a very successful series, this volume addresses not only traditional areas such as atomic structure, defects, alloy development, phase stability and mechanical properties, but also goes a step further to promote the utilization of ordered intermetallics, with research on processing, environmental resistance and applications. Topics include: defects; iron aluminides; titanium aluminides - dislocations and atomic structure; nickel and iron aluminides; NiAl - dislocations and atomic structure; titanium aluminides -fracture and creep; NiAl - mechanical properties and processing; titanium aluminides -dislocations and interfaces; Ni3Al -dislocations and atomic structure; titanium aluminides-processing; Ni3Al -mechanical properties and processing; silicides; titanium aluminides and exotics; environmental effects and surface treatments; trialuminides and Ti2AlNb; oxidation; and niobium aluminides and laves phases.
