Kinetics of carbide precipitation in Cr-Mo steels

• IdentificationGA106/00/0855 FundingStandard
  Project GA CR
• Duration2000 - 2002 Project leader Rudolf Foret
  (TU Brno)
• Co-leadersDr. 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
  700-500C.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.
