..., definition of transition temperatures, as well as upper and lower shelf energy levels were followed, and different scaling procedures were applied to the sub-size test piece results. The results show that proportional scaling of sub-size to full-size test piece results in terms of KV should be disallowed...

...GS Bhuyan The galvanizing process shifted the scatter band for impact energy values of the CSA 350 WT, category 4, plate material by approximately 10°C. The cold-straining alone produced the most significant shift (30°C) in the ductile-to-brittle transition temperature. This particular steel...

... of strength levels. Charpy transition temperature curves were developed for each condition. SEM fractography was used to analyze the fracture behavior of the various heat-treated structures. The results show that AISI 8640 steel with high phosphorus and high arsenic was embrittled in the low-strength bainitic...

.... Arsenic is also believed to be involved in the embrittlement effect, specifically as related to producing a reduction in the upper shelf Charpy impact energy. Embrittlement was manifested by a reduced fracture toughness, an increase in the Charpy transition temperature, and intergranular fracture. 18...

... to neutron radiation exposure or both. This report represents the opinion of MPC Subcommittee 6 concerning the predictability of the shift in the brittle-ductile transition temperature based on data available as of November 1977. The data are presented as three sets of curves: total data base, experimental...

... that incorporated a temperature shift to relate impact to static data gave slightly better estimates of K Ic values in the transition temperature region than the others. However, the best results over the widest temperature range were obtained from a correlation method based on a J integral estimation that predicts...

... variations. Several areas are reviewed to identify conservatism and the sensitivity of structural integrity evaluation results to the property variations. The areas reviewed were fluence dependence of the transition temperature, fracture toughness, the drop in upper shelf toughness, the arrest toughness...

... was found to be useful in reproducibly determining fracture energy and transition temperature. Difficulties were encountered in pressing the notch tip to the specified depth range, and the method has been modified. Dynamic tear absorbed energy was not significantly affected by testing machine type or impact...
