STUDY ON STRUCTURAL EVOLUTION OF NO.2 STEEL TUBE MATERIAL DURING HIGH TEMPERATURE AGING PROCESS[J]. Thermal power generation, 2005, (1): 12-15. DOI: 10.19666/j.rlfd.2005.01.004.
Directing against low carbon steel No.20 commonly used for pressurized containers
pipelines
and steam conduits
the structural evolution has been simulated by adopting accelerated aging method. Results of study show that the main microstructural evolution feature of low carbon steel No.20 to be pearlite spheroidization
carbide eduction on grain boundaries
and a dynamics equation of grain size growth for the said steel in accelerated aging process has been primarily established.
