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 ...

High strength low-alloy steels impact toughness assessment at different test temperatures [PDF]
Advanced Technologies & Materials, 2021 In many production processes, as well as in the exploitation of machine components and structures, materials are exposed to impact loads. In structures made of welded joints of high strength low-alloy steels with their constituents (parent metal, weld metal and heat-affected-zone), the toughness test determines the tendency of steel to brittle fracture,
