Grain Boundary Phosphorous Segregation and Its Influence on the Ductile Brittle Transition Temperature in Reactor Pressure Vessel Steels

A Kimura, M Shibata, R Kasada, H Nakata, K Fujii, K Fukuya
Journal: Journal of ASTM International
Publisher: ASTM International
Article Type: Research-Article

... for 1000 h, respectively. The ductile-brittle transition temperature (DBTT) was measured for the aged specimens, and the ΔDBTT of 15K was observed only for the specimen aged at 450°C for 3000 h, although no changes in the hardness and tensile properties were observed. The grain boundary fracture ratio...
