✦ Synopsis

A large number of materials have a highly degenerate ground state and therefore a complex microstructure. Because of this degenerate state, phase transitions between the different phases play an important role. High resolution techniques in electron microscopy and nano-scale chemical analysis allow to study not only the microstructure but also the interfaces down to an atomic scale. We focus particularly on the ambiguity of alloys on approaching the phase transition. The short range order (SRO) in "1 1/2 0" type alloys and the microstructure of "tweed" and needle formation in martensite like alloys with composition NisAI3 are considered in more detail.
