One of the most fascinating and intriguing aspects of natural
phenomena is that complex systems may undergo symme try-breaking
instabilities leading to pattern formation or coherent temporal
behavior over macroscopic space and time scales. Therefore the
understanding of why order may appear spontananeously in open
systems far from equilibrium and which planforms are selected among
a large manifold of possi bilities has become a major theme of
research both theore- cally and experimentally. These studies,
first related to fundamental questions, appear now to be of
technological importance, especially for materials science
problems. Effectively during the last years, the whole field of
materials science experienced a complete renewal. By using
techniques able to operate in strong nonequilibrium conditions and
hence to escape from the constraints of equilibrium thermodynamics,
totally new mate rials structures have been processed. Such
techniques inclu de ion implantation, laser beam surface melting as
well as electron beam heating. For example, ion implantation proces
sing is able to create surfaces with compositions markedly
different from the bulk, leading to materials having new electric,
magnetic or chemical properties. In laser annea ling, after the
tremendously rapid melting and recrystalliza tion of the sample
surfaces, microstructures with superior resistance to friction,
corrosion, *** are frozen into place. Rapid solidification of
alloys trigger the formation of quasi-crystalline structures. Ion
beam mixing can modify the electrical properties of polymers or
improve the adhesion of metallic films to ceramics.
