Identification:GA106/00/0855
Funding:Standard Project GA CR
Duration:2000 - 2002
Project leader: Rudolf Foret (TU Brno)

Co-leaders:Dr. Ales Kroupa (ASCR), Dr. Jiri Sopousek (FSci MU Brno)

Project Description: The project deals with kinetics of important classes
of Cr-Mo steels having great importance for many industrial fields which
are used at temperatures 700-500°C.The main attention is aimed to the role

of the initial material state, changes in the microstructure 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 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.
