... the broken halves of surveillance specimens, are necessary for the efficient determination of the master curve from the limited volume of the available materials. In this study, fracture toughness tests were conducted for typical Japanese RPV steels, particularly SFVQ1A forged and SQV2A plate materials...

...Xiaoling Zhang This paper presents the common failure mechanisms of high temperature rotors and the engineering approaches to their remnant life prediction. In fatigue crack growth at the rotor bore, cracks from original forging defects or induced during long service life may grow under cyclic...

...B. Scott Kessler; A. Sherif El-Gizawy; Douglas E. Smith The accuracy of a finite element model for design and analysis of a metal forging operation is limited by the incorporated material model’s ability to predict deformation behavior over a wide range of operating conditions. Current rheological...
