The project deals with kinetics of very important classes of Cr-Mo steels having great importance for many industrial fields which are used at temperatures 700-5000oC.The main attention is aimed to the role of the initial material state, changes in the m icrostructure and population of precipitating phases at annealing temperature and to the states close to equilibria. The industrial and modelling materials will be investigated. The different heat treatment will be used for sample preparation in order to obtain few types of the initial microstructures. The kinetics phenomena will be investigated experimentally and complemented with their theoretical description. The diffusion and phase diagram calculation will be also performed. The experimental data wi ll be used for parameter precision of the used theoretical models. The few year exposed equilibrated samples of industrial steels are at disposal and it is supposed to obtain reliable information concerning the states close thermodynamic equlibrium, too.
