Interface segregations in other materials have also been investigated. Horton Miller41 studied segregation of boron to the grain boundary and antiphase boundary in rapidly solidified ordered Ni3Al alloy doped... 

In compositional analysis of very small precipitates, or in interface segregation studies, using a probe-hole type atom-probe, one is always faced with the fact that the probe-hole may cover both the matrix and the precipitate phases, or the interface as well as the matrix. Thus any abrupt compositional changes will be smeared out by the size of the probe-hole and also by the effect of ion trajectories. A similar uncertainty seems to exist in the compositional analysis of nitride platelets formed in nitrided Fe-3 at.% Mo alloy, aged between 450 and 600°C, where Wagner ...

Often, however, it is more realistic to abandon the model of a discontinuous interface. Segregation of impurities and other point defects, as well as elastic and electric fields, broaden the interface region. For this extended boundary, we can formulate j the Gibbs energy of Eqn. (10.1) as (< = A,B) j... 

The Interface-Segregation Principle Clients should not be forced to depend on methods that they do not use. 

It is instructive at this point to review the equilibrium or nonequilibrium thermodynamics governing interface segregation.

The main point established up to now is that amphiphilic molecules tend to form an interface when put into contact with a solvent preferring one of their sequences. This interface segregates the two sequences, thereby producing an interfacial film. The film may have variable curvature and its properties depend on temperature in a way determined by the liquid or solid state of the chains.

Impurities dissolved in the liquid can influence and are influenced by the solidification process [7]. Trapping, dependence of the interface segregation on the velocity during resolidification, instabilities of the planar interface and formation of cell structures represent another area of interest to the meeting and some relevant experiments will be described. At this stage we prefer, in view also of our background to point out mainly, the experimental results and a simple thermal treatment [8].
