Principle Problems in Phase Transformation Phenomena

The considerable and programmatic reasons for an improvement of the theoretical base in recently most rapidly developing segment of science - the materials engineering - where controlling of the process of creation of a new usable material acquires presently a reasonable meaning in the world, have been discussed in this paper. Also has been presented some new proposition of an approaching to the question basing on the idea for organisation of an intellectual structure, jointing the activities of an existing group of theoreticians and experimenters, for whom the controlling basing on new theories become an important impulse and a strong instrument helping in the achievement of the above aim. It is considered that the proposition for formulating of some central limit theorem (CLT), that will correspond to some technological process on the level of a small set of particles which can grow thick in its structure, passing into infinitely increasing number of particles by the way in known continual process, described, for example, by known differential equation - that it is a proper way for recognition of what is going on in the nano and microstructures determining the nucleation and the growth of the crystals. It is assumed that in a case of appearance of some constructive reactions to the doubts discussed in the paper, it is a chance for establishing a suitable group of person discussing above problems and being able to create the theoretical description as well as to gain effectively new technical solutions, useful in the further, successful development of the materials engineering in the world.
