چکیده انگلیسی
Effect of 'conventional normalizing and tempering' (CNT) and 'double austenitization based normalizing and tempering' (DNT) process on microstructure characteristic and mechanical behavior was studied forP92 steel. In CNT heat treatment, P92 steel is normalized at 1040â¯Â°C/air cool and tempered with 760â¯Â°C/2â¯h/air cool. In DNT heat treatment, initially normalizing was performed at 1040â¯Â°C for 1â¯h followed by water quenching. After that sample was normalized in the temperature range of 950-1150â¯Â°C for 1â¯h and tempered at 760â¯Â°C/2â¯h/air cool (950â¯Â°C-DNT1, 1050â¯Â°C-DNT2, 1150â¯Â°C-DNT3).Grain size for CNT and DNT1 treatment were measured 17â¯Â±â¯7â¯Î¼m and 12â¯Â±â¯5â¯Î¼m. A DNT treatment resulted in homogeneous microstructure formation that led to improved mechanical properties as compared to CNT treatment. The DN based heat treatment produced complete martensitic microstructure formation by complete dissolution of carbide precipitates. The optimized room temperature condition was obtained for the DNT 1 heat treatment.
