Microstructure Degradation after Prolonged Exploitation of Heatresistant Steel 14mov6-3
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 6
Abstract
Metallographic testing of material microstructure represents important method for characterization of material behavior. In case of heat resistant steels that are used for steam lines and boiler components of thermal power plants for a long period of service time, under the influence of mechanical and thermal loads their microstructure will be changed. As a result, it will have significant influence on mechanical properties of such material. Metallographic testing can be used for following of microstructure evolution and estimation of components further safe service time, but at the same time knowing of changes in material microstructure is necessary for better understanding of mechanical properties degradation mechanism. Microstructure as indicator of material degradation of heat resistant streamline steel 14MoV6-3 after almost 200.000 hours of exploitation at steam temperature 540 °C and pressure 13,5MPa has been investigated in this paper. It is necessary to emphasize that this streamline has been designed for service life time of 100.000 hours for mentioned steam parameters.
