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

Open 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 ...
