Procedia Structural Integrity, 2016 AbstractIn this paper, an engineering framework to transfer the lower bound fracture toughness between different temperatures in the ductile–to–brittle (DBTT) temperature region is proposed and validated for 0.55% carbon steel using 0.5TSE(B) specimens. The framework requires only stress–strain curve for different temperatures as experimental data. The

Recent Improvements in Size Effects Correlations for DBTT and Upper Shelf Energy of Ferritic Steels [PDF]
, 1993 Currently available correlations for the effects of specimen size on the upper shelf energy (USE) were developed for relatively ductile steels and do not serve as well when the steels become embrittled. Size effects correlations were developed recently for the impact properties of less ductile HT9 to be applied to other initially more ductile steels as

steel research international, Volume 94, Issue 2, February 2023., 2023 The initial crystallographic orientations are changed along with the tensile directions, inducing the difference in mechanical properties and strain‐induced martensitic transformation rate in 304 austenitic stainless steel. Especially, high strength and ductility at both room and cryogenic temperatures are achieved when the material has more volume ...
