Abstract
Jekla, ki se vgrajujejo v termoenergetske objekte, so med obratovanjem izpostavljena dolgotrajnim termičnim in mehanskim obremenitvam. Zaradi tega nastajajo v jeklu različne mikrostrukturne in mehanske spremembe, kar ima za posledico spreminjanje prvotnih lastnosti cevi od vgraditve dalje. Za boljše razumevanje teh procesov sta bila raziskana vpliv temperature in časa izotermnega popuščanja na spremembe mikrostrukture ter kinetika izločanja in rasti karbidnih in drugih izločkov.

Title:Investigation of the microstructure of X20CrMoV121
Abstract:
Steels in thermal power plants are subject to long-term thermal and mechanical stresses. This induces different types of mechanical and microstructural changes and a continuous change of the steel pipes' properties. To understand the processes involved in these changes, the influence of the temperature and time of isothermal annealing on the microstructure changes as well as the kinetics of precipitation and the growth of carbides and other precipitates was investigated.

Keywords:high-temperature resistant steels, isothermal annealing, carbide precipitates
