Impact Toughness Modification of NIST Low-Energy Charpy Verification Specimens for Testing at Room Temperature

open access: yesJournal of Research of the National Institute of Standards and Technology, 2017
The possibility for the National Institute for Standards and Technology (NIST) to certify Charpy reference specimens for testing at room temperature (21 °C ± 1 °C) instead of −40 °C was investigated in a previous study, in which a slightly increased likelihood of specimen jamming was observed at the low-energy level (13 J to 20 J). Moreover, there is a

Low temperature impact toughness of the main gas pipeline steel after long-term degradation [PDF]

open access: yesOpen Engineering, 2014
AbstractThe correlation of microstructure, temperature and Charpy V-notch impact properties of a steel 17G1S pipeline steel was investigated in this study. Within the concept of physical mesomechanics, the dynamic failure of specimens is represented as a successive process of the loss of shear stability, which takes place at different structural/scale ...
